Anilao 2024
20 pointsA few pictures from my trip to Anilao (Philippines) in September 2024. Unfortunately the weather was very bad and we had high water temperatures, too. So there were not that many critters around as I was used to. Also Blackwater diving was not possible because of the weather. Equipment used: Nikon Z8, Nikon Z 105mm Macro, Nikon 8-15mm Fisheye with 1.4TC (first picture); Trioplan Copy (last picture) Seacam Housing, Seacam D150 Strobes, Retra Snoot20 points

Upcoming Server Upgrade 😳
15 pointsHey everyone, I’m excited to share that I’ll be upgrading our forum software to the latest version soon. This is a major update focused on backend improvements, enhanced security, and overall modernization. While I’m working hard to make the front end as close as possible to what we’re all accustomed to for this initial migration, you will notice some changes. Here’s what to expect: Classic and Modern ThemesThe current look and feel of the forum will be called “WPX Classic” and will remain the default for now. After the migration settles, I’ll introduce a “WPX Modern” theme. You’ll have the option to switch between Classic and Modern based on your preference. Even in the Classic theme, the forum will gain a more modern, functional experience. Key ImprovementsWhile there is an endless list of little things that are improved on the front & back end, here are a few of the key improvments. Mobile: A significantly improved mobile browsing experience and App Setup. Dark Mode: A native dark mode option will be available from launch. My Streams Menu: A customizable view for sorting articles, posts, topics and even tags, moving beyond just showing “Unread All.” Performance Improvements: Along with the software upgrade, I’m also moving the forum to a new server. This upgrade to both the software and hardware should provide noticeable performance improvements. While things have been running pretty well, now is the perfect time to make these enhancements. Future Customization: This upgrade will enable us to introduce and customize future enhancements on both the back end and front end, giving us greater flexibility to adapt and improve over time. Temporary ChangesTags: Tags will be temporarily disabled at launch but will return soon as we digest how to use in the new system. The updated tagging system will be more useful, allowing features like creating streams based on tags and following your preferred tags. The store will not be available initially after the migration. A new store will be launched soon. Downtime InformationThis migration is a large and complex task. I estimate that the forum will be offline for up to 4 hours during the update. I’ll try to keep the site accessible in guest mode during this time, but you won’t be able to log in. Migration TimelineThe update will take place between April 12th and 15th. Once I finalize the exact date and start time, I’ll post an update here. I’ve already done a few dry runs, and I’m confident it should go smoothly. Thank you for your patience and understanding as we work to bring you these exciting updates. I’m confident this upgrade will not only enhance our community now but also set the stage for continued improvements and useful features in the future, providing a more secure and customizable platform for everyone. I think thats it for now.. Stay tuned for more details.15 points

Winner Overall of the 2025 Australian Geographic Nature Photographer of the Year
We are proud to announce that the winner of the 2025 Australian Geographic Nature Photographer of the Year, Overall category, is our fellow member Ross Gudgeon for his photograph titled "Fractal Forest". Fractal Forest - Macro By Ross Gudgeon, Western Australia From the 2025 Australian Geographic Nature Photographer of the Year announcement: The overall winning shot, Fractal Forest, skews perception and leaves us questioning reality with an inside-out view of a cauliflower soft coral, captured by Western Australian photographer Ross Gudgeon in the Lembeh Strait of North Sulawesi, Indonesia. Our judges remarked that the photograph gives us a unique perspective on coral, with the photographer taking us out of the marine habitat into a whole new world. There’s nothing fake here, but still we ponder, is this nature or a painting? Technical details: Inside-out view of a cauliflower soft coral. Named for its characteristic appearance that resembles a cauliflower, with numerous small, rounded, bump-like polyps that give it a puffy texture. This unique perspective was made possible by the Nauticam EMWL, an underwater version of the probe or insect eye lens. Lembeh Strait, North Sulawesi, Indonesia Sony FE 90mm F2.8 Macro G OSS with Nauticam EMWL wet lens, 1/100, f/9, ISO 400, Sony A7RIV, handheld, 2 x Retra Pro flashes.

Nauticam USB-C bulkhead mini review
14 pointsBefore my most recent trip last year I purchased the Nauticam USB-C bulkhead for my OM-1 housing which uses the M24 bulkhead on the housing. The setup consists of an M16 bulkhead and a specific M24-M16 adapter that is machined so that the right angle USB plug will fit through. In summary it works as advertised, I can charge the camera without breaking the vacuum and also download images. Download is a little slow compared to using a card reader it seems the limit is set by the camera interface. I achieved around 28 Mb/sec, while I can achieve 150 Mb/sec with my card reader. Battery charging seems to be about the same as plugging the camera directly into a charger. I got the bulkhead as I shoot the Canon 8-15 with metabones adapter, which requires placing the camera in the housing then assembling the lens from the front placing the dome over the installed lens. This takes some time to pull apart and re-assemble, so being able to charge and download without opening is one less thing I need to deal with each evening after diving. Here is a couple of photos of the bulkhead installed, it seems to be a high quality cable. and externally the bulkhead uses a sealed cap similar to a vacuum valve to protect the USB terminal inside. It is sealed so holds a vacuum if the cap is removed. Overall I'm happy with it as it does what it's meant to do.14 points

Mafia Island: a diving destination away from the tourist crowds but rewarding for UW photographers
14 pointsMafia Island is located in the Indian Ocean, off the East African coast of Tanzania. I learned about Mafia Island from reports of several scubadivers in internet platforms, who consider it an “insider tip”. In November/December 2024 three divers (Lisi, Franz and me) set out towards Mafia in order to experience firsthand the diving and possibilities for UW-photographers. Mafia Island is not difficult to reach via international flights from Vienna/Austria to Dar es Salaam/Tanzania. From there, the travel continues with a short 30’ flight via domestic airline. The airport in Kilindoni, the largest village of the island, is small and, accordingly, the airplanes are small too (the photo shows the main building of the airport and, to the left, the nose of the aircraft that brought us there). By default, only 15kg of luggage, including the cabine luggage, are allowed in the small aircraft. It is very positive to note, that one can book extra luggage in advance by EMail with the domestic “Coastal Airline” (https://coastal.co.tz/), in order to avoid unpleasant surprises when arriving with masses of unannounced luggage. This way, our extensive diving and photo equipment was “nullo problemo” (in order to avoid overload of the aircraft, we had to book an extra seat in advance, that remained empty). There are several resorts located on Mafia Island, but only a single one, “Big Blue Mafia Island Diving Centre” (https://bigblumafia.com/) is perfectly positioned within the Mafia Island Marine Park, where most of the diving spots are located (the marinepark fee, that has to be paid for every single day of the stay once upon entrance, is worth every single cent). This resort is owned and managed by Maura, an Italian, who is the friendly contact person for booking and payment. She is married to a local diving instructor, native to the island, who runs the diving base (their son is working as diving guide, one can say it is a true family enterprise; also the other instructors, guides and employees contributed to a very pleasant stay including safe and wonderful diving). Accommodation is simple, but corresponds to western standards, comprising tasty half (or, when required, full) board and aircondition. Cleaning and freeing the huts from mosquitoes with pesticides is done twice per day. At this point it is appropriate to mention that effective repellants and malaria prophylaxis are strongly recommended by our Austrian tropical medicine specialists. Diving is done using Dhow style boats, that provide plenty of space for the few divers. They are made from heavy tropical woods and are powered by an outboard engine. When winds allow, the boats are also able to sail along silently and swiftly. Chole Bay is the heart of the natural reserve and accordingly most diving spots are located within the bay. Depending on weather, diving spots outside the bay can be dived also. Since the tidal range within Chole Bay is substantial, departure times for the two-tank boat dives are dominated by the tide, are highly variable from day to day and were between 05:00 AM and 14:30 PM during the two weeks of our stay. Despite careful consideration of tidal times, substantial currents are possible. At low tide the visibility within the bay can be pretty modest (as low as 4-5m), but at high tide and also outside the bay it can be remarkably good (up to 30m). Taken together, the diving conditions are certainly not easy for UW-photographers. This is more than compensated by outstanding biodiversity and abundance of species that guarantee the presence of great motifs in high number, rewarding those that take up the challenge. School of common blue-striped snappers (Lutjanus kasmira), outside Chole Bay. Sony A7R5, WACP-C, Sony 28-60mm @28mm, 1/160s, f/10, ISO 100, 2* HF-1 (4500K diffusers): Also inside Chole Bay, the quality of hard coral is good. Sony A7R5, Canon 8-15mm @15mm, 1/100s, f/10, ISO 100, 2* HF-1 (4500K diffusers): Attracted by me, since I was using the macro setup (when I was equipped with the fisheye lens, mating Nembrothas were almost guaranteed), a giant Potato Grouper (Epinephelus tukula) shows up inside the bay. Sony A7R5, Sony 90mm macro, 1/200s, f/9, ISO 100, 2* HF-1 (4500K diffusers): The diving comprises plenty of motifs for wideangle photography, but Chole Bay can be regarded as a true macro destination for UW-photographers as well: Numerous nudibranch species can be encountered around Chole Bay. Noteworthy to state, our stay coincided with the mating season of the Golden Nembrotha (Nembrotha aurea). These seaslugs are hermaphrodites and mating takes place by connecting the sexual organs, located on the right side of the body, with each other in order to transfer the sperm. Sony A7R5, Sony 90mm macro, SMC-1, 1/250s, f/14, ISO 100, 2* HF-1 (4500K diffusers): Blue Pseudoceros flatworm (Pseudoceros bifurcus) moves leisurely over hard coral.

Sony A7R5, Sony 90mm macro, 1/250s, f/13, ISO 100, 2* HF-1 (4500K diffusers): Longnose Hawkfish (Oxycirrhites typus) sitting on black coral. Sony A7R5, Sony 90mm macro, 1/200s, f/13, ISO 100, 2* HF-1 (4500K diffusers): Reef octopus (Octopus cyaneus) peeks out curiously from its shelter. Sony A7R5, Sony 90mm macro, 1/200s, f/18, ISO 100, 2* HF-1 (4500K diffusers): A report about diving at Mafia Island cannot be complete without whale sharks (Rhincodon typus). Outside the marinepark, between the African eastcoast, where the impressive Rufiji river ends up in the Indian Ocean, and the west coast of Mafia Island, the Mafia channel is formed. The high input of biomass from the Rufiji river delta causes plankton to bloom within this strait. This results not only in poor visibility (6-10m; and hence (again) challenging conditions for UW-photography), but, at certain times of the year, whale sharks gather for feeding. Snorkeling excursions by boat are offered and we were able to spot up to 15 different whale sharks on a single day (including a touching encounter with a female shark, closely accompanied by her half-grown up offspring). Whaleshark feeding on krill. Sony A7R5, WACP-C, Sony 28-60mm @31mm, 1/200s, f/7.1, ISO 200: Whaleshark fading away into the blue. Sony A7R5, Canon 8-15mm @15mm, 1/250s, f/6.3, ISO 250: It was an unforgettable diving trip and fond memories will endure. We already have booked flights and resort for another two weeks in November 2025, in order to visit again this little paradise… 😊14 points

Video: Tresher Sharks and more...
14 pointsHi, i went back to Malapascua Island after 17 years to see Tresher sharks. We saw up to 8 Tresher sharks cruising together in one spot. Luckily i spent 2 weeks in Malapascua, (compared to most other divers who stay only 2 or 3 days), because the viz varied from 25 to bad days 10-12 meters. Afterwards i visited Moalboal to get some Sardine school shots. Enjoy watching! Alex.14 points

MFO-3 with Olympus 60mm macro
13 pointsStarting a new thread to do a quick review of using the MFO-3 with the Olympus 60mm macro. The 60mm is commonly used on m43 setups as the usual macro lens, it's quite sharp and AF is quite good on later bodies but it's a bit on the long side at 120mm FF equivalent, so larger subjects require backing up a lot with a lot of extra water in the way along with all the particles to make backscatter. The MFO3 reduces the field from that of a 60mm lens to about 37 mm focal length increasing diagonal field from 20 to 33 degrees. I used it for the first time in Lembeh Strait this week, popping it on to shoot things like Lionfish, anemone fish and other larger subjects like big cuttlefish. The extra field of view is significant and allows you to shoot these subjects with a lot less water between you and the subject. I found the field to be quite sharp into the corners when reviewing on my laptop and the subject really was very sharp. AF was pretty snappy as well. In Lembeh where you might be shown a tiny emperor shrimp followed immediately by a 200mm long scorpion fish or cuttlefish it was really very useful, in fact I'd say it was indispensable. I carried in a pocket on a pair of cargo shorts complete with bayonet mount and found it easy to get out but a bit trickier to get back in with one hand. I took the supplied neoprene pouch on the boat and after rinsing stored it in there to stop it drying out. some examples: Weedy Rhinopia - slight crop: A False clown anemone fish, I would normally crop and get in closer but this shows the sharpness across the frame: A Trumpetfish which was about 500mm long : A zebra lionfish, cropped slightly: Hopefully this gives some idea what the lens can do. The only real downside is the bulk of the lens, it a big lump but easy to use with bayonet mount. The pics were chosen to show the versatility I found. Lens supplied by Scubapix, the Australian Nauticam distributor it was from the first batch imported. I paid for the lens my myself. Let me know if you have any questions, hope the review is useful for those considering it.13 points

What new flashes???
13 pointsHello everyone, I've now completed 20 dives with my two new AOI UIS-P1 Ultra and i am absolutely satisfied with my purchase decision. I've used the flashes both in the lake and now in the Red Sea, and I can only say positive things about them. They're fast, easy to use, and they have a lot of power! Even with dry gloves, the flashes are easy to operate. The displays on the back of the flash provide information about the status, battery life, etc. When the flash is firing at full power in TTL, an audible signal is given. Along with the new flashes, I also replaced my flash trigger and treated myself to a Backscatter Smart Control TTL trigger. This is also excellent, and I shot most of my images using TTL, and it works fantastically. For me, the big advantage of the backscatter trigger in the Nauticam housing is that there are no cables going up to the LEDs, which makes the whole process of installing and removing the camera from the housing much easier.

Imperial Residence - Emperor Shrimps on their Nudibranch Home (Okinawa main island, Japan)
13 pointsHere’s a little clip I shot this week on Okinawa Main Island’s Pacific coast (Kin Red Beach) — a classic but colourful commensal / symbiotic combo: Emperor shrimps (Zenopontonia rex) riding their lofty nudibranch palace (?Ceratosoma trilobatum?). Edited to “Raindrop” by Tomotsugu Nakamura (sound on if possible) This was shot on my old Lumix LX10 compact in 4K/30fps, using either the Nauticam CMC-1 alone or stacked with a UCL-165 close-up lens. Lighting was from two Kraken Hydra 8000 V2 lights and one Backscatter MW4300. There was a bit of water movement and suspended silt, so I'll need to be more careful with light placement next time using the triple-light setup... Cheers and happy bubbles, Ben13 points

It's Time to Talk About the Nikonos RS 13mm Again
With a small "dome" of less than 4in/100mm, the RS 13mm is never going to be as good for splits as a large dome. A large dome makes the water line smaller and easier to keep positioned where you want it - especially in wavy conditions. A large dome also decreases the focus difference between underwater and topside portions (so the topside is less blurry). That said, splits are possible with the RS 13mm, and a small dome actually has a couple of advantages in that you can do splits of smaller subjects and in shallower water. Here are a few examples. Note that I didn't stop down the aperture very much for these (f/5.6-f/.8). Obviously, shooting at something like f/16 would give a less blurry topside if that's what you're going for.13 points

Video: Cocos Island Costa Rica
12 pointsHeres a video from my recent trip to Cocos. It was my second time at Cocos since 2006. We saw six different shark species, but seeing & getting good footage are two different things. As you know, sharks are shy when there is no bait in the water, even the big Tigers. I also saw big Hammerheads schools twice. The first time i had an 18mm WW lense set up (the first time after a few days because the second dive was planned at an arch. I switched lenses too early – a big mistake). I saw the HH school swimming in shallow water, while i stayed at 25-30m at Alcyon. I filmed them, but they looked like ants in the footage…The 2nd time at Alcyone with the proper 28mm lense…the HH school in shallow water again, but too strong current during descent…no chance to set and focus on the camera, as i reached the bottom the sharks were gone I uploaded directly from DVR in 4K on YT. The 4K video has only 360MB…that resulted in some color banding in the uploaded YT clip, which i don´t have in DVR with a 16bit color depth cam or rendered in decent 4K resolution. No slow-down uw footage in post.12 points

Preview of the MFO-2 - Now called MFO-3
12 pointsA point worth raising is that it is difficult to do really precise test shots with and without the MFO-2. I just wanted to highlight this issue – as surely many with and without shots will be shared in the coming months and you should look at them bearing in mind the difficulty in having a consistent methodology. The problem is two fold. First, the addition of the MFO-2 requires the camera lens to refocus (because of the Focus Optimizing stuff). For test shots this means you can’t simply use a fixed focus on the camera to do a with and without shot. And second the MFO-2 is a macro lens and is very long. I have been doing with and without shots keeping the camera a constant distance from the subject. Theoretically, you might think that it is best to keep sensor to subject the same for both shots. However, because the MFO-2 is so long (and we’re shooting macro here) the front element ends up much, much closer to the subject, than the bare lens. So it has been suggested that it would be a better test to keep the front element of the bare lens and the MFO-2 the same distance from the subject – as this is often the limiting factor in underwater photography – both when approaching as subject as closely as possible and also for shooting through as little water as possible. But doing makes the MFO-2 looks a lot, lot wider than the straight macro lens (because the camera has to be moved further back from the subject). The MFO-2 is already a lot wider! There is no perfect way to show/shoot with and without MFO-2 images. All I can say is that when you put it on it does make a really significant change. This test shot was done with the keeping the sensor the same distance from the subject (keeping the camera in the same place) – although I accept this means that the front element of the lens of the MFO-2 is much closer to the subjects, than the standard lens (so for some this underestimates how much wider it makes the view). Without MFO-2 With MFO-212 points

Raja Ampat, Misool and Triton Bay with Emperor Divers
I've just got home from a terrific 12-night Raja Ampat trip on Emperor Diver's vessel, MV Harmoni. The itinerary started in Kaimana, covered Triton Bay, Misool and the Dampier Straits - and ended in Sorong. Others have written about the diving delights of the area so I won't rehash that. Suffice it to say that, my first trip to this part of Indonesia, I found the diving just fabulous. Abundance and variety of marine life was something else. Whale sharks and mantas included. I've been fortunate to have been on lots of liveaboards over the years. This was, by far, the best I have ever done. Harmoni has a crew of 21 for 24 guests and is spacious,. comfortable and relaxed. Lead by a first class Cruise Director, the entire crew were unfailingly helpful and considerate. We splurged and got an Upper Deck cabin. This was roomy with a ?king-size bed (depending on what side of the Atlantic you live), sofa, wardrobe and a bathroom that two people could actually use at the same time, tons of hot (and cold) water and quality shower and hair gels. I'm not sure if it is a blessing or a curse, but Harmoni has Starlink WiFi which is included in the trip price. So if the mood takes you, internet is available in the galley at all times throughout the trip. It reaches some cabins too. Diving was from a RIB with four guests accompanied by a dive guide. Nitrox was included in the price. Following the usual briefing, divers put on their wetsuits and only had to carry their mask and camera to the RIB. All gear was loaded by the crew with divers being helped into their BCs etc on the RIB immediately before a backward roll onto the divesite. No carrying heavy gear down to the RIB or down to a dive deck. Luxury. A dive guide was assigned to each group of four and rapidly understood what the group wanted to do in terms of photography, ease of the dive, avoidance of current etc. Dive sites were usually 4-5 minutes (enjoyable) RIB-ride from Harmoni with at least one RIB monitoring the dive with several ready for pick ups at the end of the dive. At the end of the drive, the crew moved dive gear, except mask and camera, from the RIB to Harmoni so, again, no lugging of gear. They even rinsed wetsuits after each dive. At the end of the trip, the crew rinsed all dive gear (apart from cameras), got it all dried and delivered into the galley for collection! Food was always excellent and a mix of Asian and European. The system was the classic light breakfast, dive, big breakfast, dive, lunch, dive and dinner. Harmoni had a well-stocked bar complete with barman and espresso machine (yay!) We used the Aston Hotel in Sorong and the Grand Papua Kaimana in Kaimana. Both were good. We flew KLM to Jakarta and then Garuda to Sorong and Wings Air to Kaimana. No problems with any of the flights and the service was always very good. On one flight there was a tiny charge for excess baggage. We applied for Indonesian visas online and were seriously impressed by the arrival formalities in Jakarta: a quick transit through e-gates. I celebrated an "x0-birthday" during the trip and cannot think of a better way of marking the occasion. I can recommend Harmoni highly.12 points

Sony 100 mm macro
11 pointsI've shot over 3000 underwater images with the Sony 100mm now. It is definitely the best macro lens that I have tried on my Sony. And arguably the best macro lens on the market. That said it is small gains over other options, rather than this being a whole new world. AF better, especially tracking and difficult subjects. Sharpness excellent, but not that different. Bokeh more attractive. The 1:1.4 range makes it very versatile - you can definitely do so much with the lens and MFO-1. Works very well with MFO-3, SMC-3 and EMWL-160 (although I find I get a bit more camera shake than with 90mm - despite stabiliser - need to check settings). The most impressive thing to be me is the performance with teleconverter. AF is amazing with TC.11 points

All set for Wide Angle but found an excellent Macro subject
Found an absolutely gorgeous Mosshead Warbonnet (Chirolophis nugator) on Sunrise Reef in Gig Harbor. (About 1 hour south of Seattle in Puget Sound.) This is one of the most amazing fish of the Pacific Northwest. With it's ornate and detailed camouflage mossy head dress, bright red color, and patterned body it's got a lot going on. This one was quite large at about 20cm and more colorful than most of its kind. So of course I had to shoot it! I was carrying a wide-angle lens setup, hoping for big GPOs and Wolfeels. Nikon Z8, 24-50mm, WWL-C port, so really not ideal for this small subject. The WWL-C optics closed the gap however! I zoomed to 50mm and flipped the sensor in the DX 1.5x crop mode to achieve a near-macro framing. My big, high-power HF-1 strobes were powered down to 1/8, angled in, and didn't blow out the scene. I'm happy with the result! Even though I forgot to roll the ISO down toward 100 for a macro subject I can't see anything negative at ISO500.

MFO-1 and focus limiter
11 pointsI shot my new MFO-1 last night with a Nikon Z8, 105mm F-mount, and Nauticam housing, dual flip with the MFO-1 and Subsee +5. Quick observations are that the Subsee is likely going on the shelf. The MFO both reduces and extends focus range to over a meter and reduces it beyond what the 105 can do by itself. The Subsee +5 has been my go-to macro accessory as it also reduces the shooting distance while not magnifying too much. However, it has a very limited range of maybe 30cm. I often have it flipped down and then mistakenly try to shoot something larger beyond its range, causing a delay to flip it up. The MFO can get in tight but also provides useful range. The first critter I spotted last night was a pretty large Pacific Ruby Red Octopus, about 12 inches long, This is about as big as they every get. I was able to take full body shots from about 1 meter away no problems. Here are two sample photos: f16, 1/200s, iso250 f16, 1/200s, iso10011 points

Epic rendezvous with Orca feeding on sardines in Norway this November
We were supposed to finish the day. On the way back to the boat I saw some action across the bay about a mile away. Like geyzers popping up all over the place. I talked others to go to check this out and the rest is history. It was the most spectacular action of our trip and as the guides put it they've never seen anything like it in years. Never mind my battery was exhausted before three humpbacks decided to end the party and splash me away :-)10 points

Starry Eyes in Kin Bay – Ornate Ghost Pipefish Clip (Okinawa main island, Japan)
Hello all, Well, I’ve been giving in to the times and working on vertical-format edits, even though I’m not really phone-oriented (I know, I know, O tempora, o mores! 😢). I thought I’d share this one here, as I’m happy with the shots - the pipefish itself is about as vertical as they come, and it was cooperative enough to let me get close for some nice details. I find the eyes, gills and tiny swimming fins rather fascinating. For the boomers and purists in the back row, a more traditional and civilised UHD edit - horizontal like nature intended - is also viewable here 😁: https://youtu.be/za96mthi8xE Gear-wise, this was shot on the ol' Lumix LX10 in 4K 30fps, with a Nauticam CMC-1 diopter, two Kraken Hydra 8000V2 lights and a Backscatter MW4300. This was filmed last week at Kin Bay, on the Pacific side of Okinawa’s main island. Cheers! Ben10 points

Fibre Optic Cables: Keeping them Happy and Firing
Some time back, I wrote an article about creating your own fibre optic cables: a quick, easy, inexpensive and very satisfying process. In case you missed it it, a link to the piece is here. https://waterpixels.net/articles/articles_technique/diy-fibre-optic-cables-easy-r32/ Now, many months on, a couple of additional suggestions: BURPING On entering the water and descending the plugs at both ends of the cables often need burping. Tiny air bubbles seem to be able to block fibre optic light transmission. Easy to resolve of course: simply remove and replace the plugs at the camera bulkhead and strobe ends of the cable. Worth checking especially before setting up for that crucial, once in a lifetime image. DAMAGING THE CABLES On a recent long dive trip in Raja Ampat, my system was being hauled in and out of RIBs with the strobe arms being moved and folded sometimes by me, sometimes by the boat crew. At some stage one of the fibre optic cables gained a small “crimp” which resulted in the attached strobe not firing consistently. Annoying of course although easy to replace the cable. This got me thinking about a way to protect the cables. For my next trip I used some cheap garden micro-watering system hose tubing to provide a protected route for the cables from the housing bulkheads to the strobes. Cost was a few cents. I found it slightly better to cut the tubing slightly shorter than the fibre cables as this allowed for easier curves at each end. The tubing is held against the float arms using short loops of bungee cord. I found it worked best to push the fibre cables into the strobe plugs only on descent or at depth. This allowed for burping and avoided any strain on the connections whilst handling during entry. In general I’ve found it better not to have fixed connections at both ends of the fibre cable. If one end can pull loose when strained, (best I've found is the strobe end) this avoids breaks and overstrains especially during transportation or in rinse tanks (avoid them at all costs!). If stretched or tugged the cable will simply pop out of the strobe end bush. No damage results and the cable is easy to push back in. The first photograph shows the fibre optic cable and the garden hose tubing; next one with the fibre pushed through the tubing; then "hung" on the strobe arms; and finally the loops to hold the tubing and cable in place.10 points

Diving with the Weefine 3000 CCW Ring Light
I have long fascinated with shooting ring lights underwater starting with the Inon Quadflash, through the various Athena modifications to Sea and Sea strobe heads, continuing to the Saga fiber optic rings and now to the Weefine 3000. The Weefine 3000 is the latest version of the LED lights made by Kraken and Weefine. The Weefine 3000 CCW Weefine 3000 CCW Ring Light It's similar to the earlier 3000 lumen LED modules but has adjustable color temperature and a 3000-lumen burst (strobe) mode. It also has a super closeup mode that can shoot subjects as close as 25 mm (1 inch) from the strobe. It is powered by a protected, 26650, 5000 mAh Li battery. The battery can be charged via a built-in USB-C port. One very neat thing about the light is that it allows for a very small, compact system underwater. No arms necessary, just the camera/housing/port and a single fiber optic cable. The light is shown below on an AOI housing for the OM-1 camera. AOI housing for the OM-1 camera with the Weefine 3000 CCW Ring Light The ring light can attach to any port with a 67 mm thread and can be rotated for any angle once attached. One nice feature (or bug) is that when you are using the light in the strobe mode, it remains on at low power to act as a focus light. During the day it was not terribly necessary but worked fine at night, although you will also need some kind of dive light to find your way. My wife said it was very easy to find me in or small group, just look for the circular dive light. How well did it work? Better than I had anticipated. Years ago, I had the Kraken version of this light, and it was fine; this version with improved ergonomics (no multiple button pushes) worked great. Here is a nice little clown (Triopha catalinae) from a dive in local Southern California waters before the Raja/Triton Bay trip on the Wellenreng. This was shot at 1/160 sec, f/7.1, ISO 200 using the Olympus 30 macro lens on an OM-1 in an AOI housing. Certainly, enough light to illuminate the subject, I slightly reduced the shot exposure by 0.1 to increase the contrast a bit. For other local subjects, such as this anemone it also worked well. This one was shot at f/5.6, 1/160 sec and ISO 200. I shot with the light quite a bit on our trip to Raja/Triton Bay. Here is a nice little Goniobranchus coi, shot with the Panasonic 45 lens, f/6.3, 1/160 sec, ISO 400. I was very close; you can see the out of focus gills. I love Christmas tree worms, here is one from Triton Bay. Same lens, 1/250, f/7.1. Here is a crinoid shrimp, same settings. I shot a lot of tiny things, but also a bunch of anemone fish. Here is a Clarke in an orange anemone. f/14, 1/250, ISO 400. Overall, the light worked well for the things I was shooting, it of course is completely useless for anything more than 250 mm (10 inches) away. The color temperature is fine but shooting in raw lets me adjust as needed. A friend used the light as a video light for a TG7 with a 52 mm to 67 mm adapter and said that for most nudibranchs the light was much easier to use than independent lights on arms. I wish it had more power, a 6000-lumen burst mode for this type of light would be awesome, but the current version is adequate for micro 4/3 shooters and awesome for the smaller sensor cameras like the TG series.10 points

Kraken KR-S160 vs Backscatter HF-1 vs Retra
I have always taken light very seriously in my photography and been willing to invest in the best strobes around, even when finances have been tight (as they often are working as a photographer). I credit using quality strobes (and me paying attention to using them well) as being a major factor in me developing a successful career as an underwater photographer. I jokingly credit Sea & Sea for my success - and their marketing machine that kept many of my competitors shooting with inferior light to me for more than a decade! The Subtronic Alpha Pro strobes were very good in their time (I also had Subtronic Alphas, Megas and Gammas - but preferred the light from the Alpha Pros). They had a pleasing quality of light, good colour temperature. I used them as my main blue water wide angle strobes from about 2000 to 2012. They were not especially reliable, and Subtronic service at that time left a lot to be desired. I used INON Z240s as macro and green water strobes during much of this period and onwards. When I could afford new strobes i chose Seacam 150s - which I got in 2012 and used these as my main strobes until 2019. These were noticeably more powerful that the Subtronics. The light was not as soft and i usually used the Seacams with diffusers on them and positioned them slightly further back from my subjects than the Subtronics. But the light is very good, colour excellent and the light went further. The Seacams were more reliable than the Subtronics, but still needed regular servicing. The battery packs and cables were their weak points. Many of my friends shot Sea & Sea YS250s at this time - but I felt that the Seacam was about a stop more powerful and had a better quality of light too. I was very happy there were so many people championing other strobes. Through much of this time I used the Inon Z240 as my main macro and green water strobes, upgrading to the original Retra flash for this purpose in 2017, I think. I went for the original Retra flash because it had better wide angle ability too, while still in a small package. I did a couple of trips with the Z330s, but these were too wide angle focused. As the Seacam 150s aged I tried the ONE UW and Seacam 160s as replacements, but settled on the Retra Pros. All there have great powerful light - but the Retra Pros did so in a smaller package and they had the most pleasing soft light in my opinion. They were also cheaper! I stayed with Pros and skipped with Pro X. I then moved to the Pro Max - the light is basically the same as the Pros, but the battery performance is way, way better. I’ve tried various Chinese circular flash tube, lithium powered strobes - Kraken 160, Supe D-Lamp and these are all fine. The light quality is good. Colour temp a bit cool. The power a step below - I think they don’t get enough light out of the tube despite plenty of power behind it. The Backscatter HF-1 is the most powerful strobe on the market currently (thatI have tried). It is fun to have so much power and I have used them in preference over the Pro Max on big animal trips like with sharks. But otherwise they tend to be used as backups or as off-camera strobes. They are powerful and reliable and I think the light is decent, but not exceptional. The light is best with the warmest flat diffusers. The Retra Maxi is slightly more powerful, but is not on sale yet. I’ve not shot the Ikelite 230 in the ocean, only in the pool, but these were a whole stop less bright than the Maxi (and therefore almost the HF-1). Also I did not try the Maxi with the final reflector set up - but as I tried it, it was very similar to HF-1. Retra say the production version will have improved quality of light. I will probably replace my HF-1s with a pair of Maxis when they are available. The brand new Retra Pro Max II pretty much matches the HF-1 in real world power, with a much better quality of light and in a smaller package. I used them on every dive on my last trip and plan to use them as my main strobes going forward. The Marelux Apollo 3 is impressive as a companies first strobe. But they are less powerful and have a poorer quality of light to the HF-1, but they are probably more powerful than my old Seacam 150s - so right up there. The light is too directional and lacks red, giving poorer colours when shooting them on the reef. The high speed shooting mode annoys me. In standard mode you can only shoot slowly, and then in the high speed mode you can’t shoot at high enough power - because achieving 10 frames a second is prioritised (a mode that did 5 frames a second at a high power would be great - but you can’t have that). It is like making a car that can do 50 kph and 200kph, but nothing in between. I also think that the Lumilink system has very limited practical use - so bulking up the strobe and bumping up its price to have this is a pity. And sadly it is also impossible to get a honest opinion on any Marelux product because the internet is filled with paid opinions. As you asked for my subjective opinion - I’d stress that this is all my subjective opinion. We’re lucky now that we have a load of strobes that are way, way better than Z240s and D1s that everyone was using 10-15 years ago. I’ve said/joked several times that the popularity of Retra strobes amongst serious shooters frustrates me - because everyone has great light now - and something that used to differentiate my work has gone.10 points

Sony 100 mm macro
9 pointsSeacam updated their port chart, and they recommend the PVL65 extension for the 100mm macro. I can confirm that a 60mm would not work. By email, Harald also recommended the PVL65+20 for the TC1.4, and PVL65+30 for the TC2.0 combos. Given what I already had, I ended up using the PVLs 45+20 for the 100mm, 45+40 for the 100mm+1.4, and 40+35+20 for 100mm+2.0. Stacking 3 extensions isn't optimal, but it works. Now for the test - I had a chance to go to the pool and play with everything. My aim wasn't pixel peeping, but to get a feel for this new gear, confirm that everything works, and see approx what magnification level I can get. Gear: A1, Seacam housing, MIP80 with extensions as above, no strobe, SMC-1. Lighting was inconsistent due to clouds so I did what I could. Some editing to try to get a consistent look across photos. All pictures use the same settings for texture (0) clarity (+10) dehaze (0) sharpening (40) and noise reduction (L15 C50). All pictures uncropped, exported at 1920px. I'm hoping the pictures show up in order. For pictures 2-9 I aimed to achieve the maximum magnification I could. Picture 1: Subject is 10cm long and has 2 rhinophores (elephantophores?) and a snout (snoot?) which is about 3-4mm. Picture 2: 90mm, 1/160, f/10, ISO 3200 Picture 3: 90mm + SMC1, 1/160, f/10, ISO 3200 Picture 4: 100mm, 1/125, f/10, ISO 1600 (inadvertently used different settings) Picture 5: 100mm + SMC1, 1/160, f/10, ISO 3200 Picture 6: 100mm + 1.4x TC, 1/160, f/10, ISO 3200 Picture 7: 100mm + 1.4x TC + SMC1, 1/160, f/10, ISO 3200 Picture 8: 100mm + 2.0x TC, 1/160, f/10, ISO 3200 Picture 9: 100mm + 2.0x TC + SMC1, 1/250, f/10, ISO 6400 (had to use faster shutter speed and bump up the iso) My perspective: this lens is going to be very fun to shoot. It is definitely faster to focus than the 90mm macro. The 100mm is slightly bigger, unfortunately it makes it tricky to take both the camera+lens out of the housing in one go, it's better to unscrew the lens first through the housing front. A battery change on a boat is a riskier operation. I love that we can natively achieve 1.4 magnification without having to add the SMC1, while keeping a greater working distance than the 90+SMC1. I also love that I can still add the SMC-1 to get an even higher magnification, whether used just with the 100mm, or with the TCs as well. Adding the 1.4x TC gives a 140mm lens, which can achieve about the same magnification as 100mm+SMC1 but is much more comfortable to handle. The 1.4x TC is light and adds weight towards the center of the camera whereas the SMC1 is heavy and off balance (I'm aware the SMC3 helps with that). And adding the SMC-1 on top of it really expands the range to super super macro Adding the 2.0xTC gives a 200mm lens. Magnification is great but the 200mm seems really inconvenient underwater, to get the whole elephant in the frame I had to move back more than I wanted, and I can see this would be both harder to frame subjects, and to position strobes. Adding the SMC-1 gives an even higher magnification as well, but the working distance was very small and getting the shot was really hard - despite perfect conditions with static subject and photographer. I can't imagine this working too well underwater. With the TCs, the minimum aperture also increases from f/22 to f/31 or f/45 so that may occasionally be useful as well. So the 100mm + 1.4x TC + SMC-1 will be coming with me to Lembeh, 90mm will enjoy its retirement. I'll keep the 2.0 TC for specific targets on local dives, like Shaun the Sheep9 points

New Seacam water contact optic
9 pointsHi all I see that Seacam has just launched tonight a new type of water contact optic seems it is designed to work with rectilinear lenses (16-35 range) and designed to give the same performance as in air. It uses an Ivanoff-Rebikoff lens system Called the Optical Precision Port it uses what looks like a relatively small flat port and a correction lens that is screwed in the front filter threads. Seems like it is very compact and travel friendly, though perhaps not particularly wallet friendly. Here is a link to their website, scroll down and click on the link "12 month practical test for some more details on the optics." A friend of mine Don Silcock did the field testing. https://www.seacam.com/de/optical-precision-port/ Believe Zeiss many years ago developed something similar for the UW hassleblad system.9 points

VANUATU LEADING THE CHARGE FOR GLOBAL CLIMATE JUSTICE
Anyone that knows us will understand how passionate we are about our little patch of reef. For years now we have been sharing our discoveries and at the same time documenting the change in the reef environment. On Sunday we were very pleased to host Associated Press Journalist Annika Hammerschlag on some guided dives to show first hand the impact of climate related change and other factors, not the least of which being crown of thorns and earthquakes! Her article has just been published in anticipation of the release of an advisory opinion tomorrow, by the International Court of Justice, on what legal obligations nations have to address climate change. Whether you are a climate change believer or not — the evidence is there – our oceans are suffering, we have witnessed it personally, we live it and we cry tears of despair at times – BUT we have hope. It has been our mission to create awareness of the wonders we have on our doorsteps! We may have our minute of fame, but for us this is a lifelong commitment, this is what drives our passion —- how can we get to the end of a generation and leave nothing for our kids and grand-kids to discover — we simply cannot and whilst we can we will be out documenting it first hand! The video and photos shared in the article except one on the screen are not ours. The jouransiot used her own camera. Thought I would share — This is where our photography is powerful!

Sony 100 mm macro
9 pointsGot the lens from Sony Italy today for testing! Using a 20 mm extension with the 90 mm port works — not perfectly, a bit too much space. (Marelux macro port is 97 + 20 extension = 117 mm;) I also tried the 32 macro port + 60 + 20 = 112 mm setup and is much closer to the glass… First impressions on the lens: the autofocus is super fast… hope to test it underwater soon…9 points

Diving South West Halmahera from Sali Bay resort - August 2025
Mid August 2025 I stayed for a weektime at Sali Bay Resort located in the Bacan Strait, southwest of Halmahera. My dates overlapped with another WP member diving from a liveaboard (who might jump in), we exchanged impressions of nearby dive sites almost in real time and got only subtle differences between resort-based and boat-based diving in the same region. Alike almost all of Indonesia this year, the weather in northern Indonesia was unsteady, with grey clouds and intermittent rain squalls. Surface conditions were exceptionally calm—some days felt like on a frozen lake or ice-skating rink. Despite the flat seas, the overcast skies muted underwater light and the absence of current on most of the dives reduced overall visibility (from 10m to 25m when the current was exceptionally present). I hired a private guide but except when a group came in, all the divers (majoritarily a european experienced crowd from Germany, Netherlands,or Italy) used the same big and comfortable boat. Up to 4 dives a day could be planned on demand. The spots we dived alternated Lembeh style black sand dives (to my surprize) and lush coral reefs sloping down to a sandy bottom. Most sites featured abundant hard corals, though broken sections were visible in places (storm or human cause?). Incredibly large and healthy coral fields contrasted with areas of rubble, suggesting a reef in partial recovery. Soft corals were not that abundant although could be very spectacular on some specific sites in teh current. I encountered zillions of small reef fish—anthias, damselfish, and purple queens—but virtually no medium-sized schooling species. Blacktip sharks appeared on almost every dive over reef slopes. Problem is that the resort dive boat avoided even mild currents, despite divers’ experience levels. On one occasion we skipped a site enjoyed by snorkeling families (with kids!) because our guide assessed the flow could be too strong. Which resulted too often on boring dives where I surfaced with 80–100 bar remaining after more than an hour underwater because I prefered to stay in the shallows with the clouds of reef fish rather than finning over semi deserted hard corals. I even found myself switching to video (for the first times in my life!) for a quick and dirty try. Exceptionally, the guides were probably not expecting it, a manageable current picked up at the house reef near Proco Bamboo Resort and litterally transformed the dive. Within fifteen minutes, corals unfurled their polyps, colors intensified, and fish activity spiked. That single drift dive was the trip’s standout. Macro was OK, one of the black sand spots hosted lots of Halimeda GPF and two wonderpus, although not as much abundance of other critters than Lembeh or Tulamben. I had hard times to have my guide confirming beforehand what was the specifity of the site we would be diving, in order to select the kind of lens I would kit my camera with (macro or wide angle). Except for some obvious sites, (black sand for Macro or Proco housereef for Wide ) Often the answer was "whatever you prefer" which in my mind didn't sound really promising in terms of critters to be spotted or for the expected reefscape. Overall this area of SW Hamahera felt like a hybrid of several Indonesian spots: • A touch of Raja Ampat’s reef structure but with fewer fish • Alor’s terrain but with reduced visibility and less colors • Komodo’s drift potential without its vivid coloration and no fish schools • Lembeh’s black‐sand sites yet lacking a dense critter populations Overall biodiversity was respectable but not as spectacular as the Indonesian marquee destinations. It really lacked the currents and the fish action. On the other hand, swiss italian owned Sali Bay Resort excelled in every non-dive aspect: • Spacious, air-conditioned bungalows with open air bathroom and a large terrace only 5m away from the sea • A dedicated camera room at the jetty for gear setup • A lively housereef with walking sharks on night dives • Fresh, varied meals (foccacia to die for) and friendly, super efficient staff The only downside was the divestaff’s reluctance to tackle currents—even when conditions were well within diver capabilities- and quite iffy Nitrox analyzers (after a the initialization readings for ambiant air randomly in between 17% and 26%, I simply set my computer to a minimal 28% ) Unsurprisingly, our return direct flight from Manado to Bali on Lion Air was abruptly canceled. They rebooked us on an earlier flight going through Makassar that departed four hours before our scheduled landing in Manado, despite a single-PNR booking from Labuha (the airport on Bacan) to Bali on Lion Group airlines. Did that raise an eyebrow on their side, I guess not even. Resolving the routing via WhatsApp took my wife seven frustrating hours. So boohs to LionAir as usual. Conclusion Halmahera is quite a long way and tedious to get to due to unmatching flight connexions (Wings air flight Manado-Labuha flies only once/day departing early afternoon, hence not allowing a same day connexion from Singapore ). Sali Bay Resort delivers top-notch accommodations, service, and easy access to calm, (too) friendly dives. However, the conservative current management and modest marine life—particularly the absence of schooling and intermediate fish—may leave thrill-seeking divers wanting. In this respect Halmahera didn't live up the hype it is currently getting. I’m torn on a return visit: the resort operation earns full marks, but I’d hope for more energetic drift profiles and richer fish action next time if there is one. Here are some shots from the reefs : all wide angle shots taken with Canon R7 / RFS 18-45 / WWL1B9 points

AA Battery : wich are the best for strobe
A few years ago, I was a Medtronic tech fellow and we had a small ($15K) grant to do anything technical that wasn't about your day job. I decided to learn about batteries, specifically about rechargeable NiMH AA batteries. I talked to colleagues who design batteries for implantable devices as their day job and they helped me build a computer controlled battery tester. I bought every AA battery I could find, lots of cheap Chinese ones, eneloops (white and black) and a bunch of no-name ones from Ali Express. Name brand batteries that were tested at low discharge currents were in fact more is better i.e., if you put them on 0.05 A discharge rates the time to a specific voltage was proportional to the stated capacity. To test utility in a strobe, I took one of my Z240 strobes to the EE boys in the lab and they pulled out the charging circuit to emulate with my computer controller. Unfortunately they were unable to put it back together and keep it dry. In any case I tested all the batteries in pairs using the charging circuit and using a fast discharge and repeated til the battery reached the test voltage. What we found was that eneloop whites (2000 mAh) got the most flashes. Eneloop Pros were occasionally a bit more and occasionally a bit fewer flashes but were quite variable. Most of the Powerex 2700 batteries got 30% fewer flashes than the Eneloop 2000s. I was surprised but when I talked to my battery inventing colleagues they said "of course, we could have told you that" internal discharge is critical. I haven't run the tests lately (the instrument had a loud beep whenever a battery test completed and my wife got tired of 3AM beeps). Bill9 points

Video: Courting Sea Snakes in Okinawa
Hello all, I'm finally getting back in the water, and here's a little clip I shot in Okinawa on my aging GoPro7, with the AOI UWL-03 wide lens and a Rosco filter, in 4K 60fps. Water might still be a modest 23°C, but spring is here and ❤️ is in the air... Courting Ijima's turtlehead sea snakes (Emydocephalus ijimae) at Gorilla Chop, Okinawa main island, Japan To get into kitchen stuff - we are on an UW imaging forum after all - this is my second dive after a long moving-to-Japan-in-winter-life-stuff hiatus, and also I'm testing a brand new drysuit, so didn't bring my faithful Lumix LX10. But I did carry my old GoPro 7, mounted with the AOI UWL03 wide lens and a filter-gel inside the housing, with the idea of testing what is one of the most promising replacements for the illustrious UR-Pro Cyan. Alas, conditions were really not ideal to test the filter gel, with cloudy murky - if slightly blueish - water and a slightly ridiculous depth ranging between 2 to 5 meters... So yes, clearly in the no-filter zone, but it is what it is, as ruthless lawmaker Mr Murphy always says... The "deeper" shots, on the sand, didn't require as much as a stretch to re-white balance in post (which does affect the highlights), and show the filter's potential a little better. I need to confirm these observations on a ̶n̶o̶r̶m̶a̶l̶ ̶ deeper dive, with a side to side test, but the Rosco seems to be the one I was looking for 🤞 Cheers and happy bubbles! Ben9 points

Diving trip report in the Philippines from 16/11/2024 to 10/12/2024
During our first stay in the Philippines, just after COVID, we skipped Moalboal. At the time, it was still "complicated" to change islands. For this trip I studied an Anilao – Romblon combo but it seemed relatively complicated to me... I gave up. Good for us with the typhoons, we would have been stuck for a few days. Anyway, we went back to Cebu again, with Moalboal and its sardines as our first stop. For the rest of the season we chose safety by returning to the Thalatta Resort south of Dauin in Negros Oriental. It was also an opportunity to re-test this hotel, following the change of ownership. For the third place, another safe bet, the Island View Beachfront Resort and its Anda Scuba Diving club. Resort at the top of our possibilities with the "real" rates and not the promotional ones we had in 2022. FYI, if you are a "returning guest" there is a small discount... but also by making a "long stay" from 7 or 8 nights. This helped us a lot, without these discounts, we would not have gone back for so long. So if you go, stay at least a week. I tried to minimize the trips but we will have done close to 600 km by car and boat. The route, once again it will be with Singapore Air that we will fly, still departing from Zurich. ZRH -> SIN 12 hours (return more than 13 hours) and a little less than 4 hours from SIN to CEBU. I always enjoy this long night on the plane where you can land, especially since on the way there and back you arrive in the early morning. Some go through Turkey when I look at the schedules, no thanks, especially if it's to earn only a few euros on the flight and then it's a hassle when arriving in Cebu at 2 a.m. For us, it was an arrival in Cebu around 3 p.m., everything went quickly and without the slightest problem. Provided that you have thought carefully before leaving to fill in the online form on the Philippine website in order to obtain a QR code that will be requested on arrival. This form, on the other hand... uh... A real hassle to fill, I had to start over a good dozen times... bugs galore. So avoid doing this at the last minute, you risk having surprises. It's a long journey, especially if you still count the journey to Zurich the day before the flight. 44 hours door-to-door on the outward journey and 56 hours from the departure of Anda for the return. Here we are at the exit of the airport and our driver is waiting to take us to Moalboal at the Cebu Seaview Resort. This will be the most difficult part of the journey. Almost 3 hours of winding roads with part of the night. But we arrive without any problem at the first stage of our journey where we will dive for 4 days. A quick dinner, before assembling the photo and video equipment... tomorrow the dive starts at 8 o'clock. With the 7-hour difference in winter between France and the Philippines, we will have to set the alarm clock... But it will not be useful, only too happy to be back in the warm waters of the Golden Triangle. In the morning, a little check of the papers (certifications and insurance) and of course the small form with liability waiver, in short, classic. Everything is very well organized, the tank are rigged on land by the divers but transported on the bankas by the many crew members and guides/instructors. Once everything is installed on the banka, the signal is given to join the boat. A small staircase to go down and then, depending on the tide, a small walk in the water to reach the access staircase to the banka. I strongly advise to wear booties, if possible with good thick soles, your feet will thank you. Here as in the other places where we dived, pebbles, corals and especially sea urchins can be formidable when accessing the boat. The first dive will be in Pescador, a small island in front of Moalboal, renowned for being surrounded by a teeming life. A few years ago there was a large sardine bar that had taken up residence there... We won't see the slightest of them, just a lot of fish. Nice dive to start our stay. After the dive, it's back to the center, everyone disembarks, there's something to make coffee or tea... but nothing to nibble on while waiting for the 2nd departure. Cebu Seaview being located more or less in the middle of the Moalboal coast we will do the dives less than 15 minutes away from sailing and just a little more for Pescador which we will do 3 times in 4 days. The conditions were not great so we only did the west side but nature is well done, it was different each time. In the afternoon there is a 3rd dive and it is possible to do night dives. We will not do it. On the second day we change guides that we will keep for the remaining 3 days. Not bad... I would say better than the first one who was an employee of the center while Cino was a freelancer. A guide with a bottle... A pleasure to dive with him. We will always leave first and will often, if not always, avoid "traffic jams" and "jacuzzis". It is therefore with him that we will make "the Sardines". Sardines... They migrated for an unknown reason a few dozen meters from the coast. This is where they are visible to divers but also to snorkelers. The number of boats on the surface made me fear the "worst", I could already see myself having to elbow my way underwater, a bit like Hanifaru Bay in the Maldives. Cino jumped us into the water first and "traced" directly to the north... small shock... "But where is he going?" and then magic sardines... sardines everywhere... thousands, sorry millions, impressive. We were the only ones for the first few minutes. Then a few divers joined us but at no time was there a crowd, really great. An experiment to be done at least once... We did it again 2 days later without any regrets. It's not easy to convey the atmosphere in photos, I did the best I could. It's up to you to judge. The dive center is not the "family" type, it's closer to the factory... but very well organized, where it is good to dive. We did 11 dives in 4 days and were happy to go to see something else. The hotel is comfortable, nothing to say, nickel, quiet and the a la carte restaurant is very good. It's not on the level of the next ones but excellent for the price. Very good mention for the bar. The cocktails are very well dosed... (I suspect the bartender reversed the dose of rum with that of orange juice... ) It was really not worth having 2 drinks to sleep well. As is often the case with great encounters during these few days, there are no regrets about having passed through Moalboal... Sardines undoubtedly deserve the destination to be bet on a "ToDo", even if bubble factories are numerous here. After 5 nights it is the departure for the Negros Oriental. The transfer is arranged at my request by the Thalatta Dive Resort. A taxi picks us up at 8 am and after about 2 hours 30 minutes we arrive at a small port where small fast shuttles go back and forth between the islands of Cebu and Negros. The crossing is done in less than 30 minutes. Remember to have Pesos (PHP) in order to pay porters and luggage tax on arrival. The whole thing cost us a few hundred PHP (1 € = +/- 60 PHP). Upon arrival, a driver is waiting for us to take us in less than an hour to the Thalatta. We will arrive in the early afternoon and will be able to sit quietly and enjoy the pool before the return of the divers who spent the day with 3 dives at Apo Island. When we arrived, we met "our" guide Nadi with whom we had dived 2 years ago. He no longer dives. Alex, the new owner of Thalatta Resort, asked Nadi to take over the reins of the diving club. He now manages the entire small team and the maintenance of the diving center. We will dive with Oien during the 7 days. He is now the most experienced guide. He was trained by Nadi. We had already dived with him during Nadi's "day off" in August 2022. He is very good and has gone out of his way to show us as much as possible.... Ouch that's where it starts to get stuck. The season is really not ideal, not too much life, few nudibranchs, shrimps and others. It's nature and you have to accept it. We are "just" a few weeks, even days before the gradual return of the little beasts. Nature... hmmm that includes the weather. Not really at the top of the wind coming from the north-east and some clouds. But overall it was very nice. A little frustrated at having been able to fly very little with the drone. Big frustration on the day of departure with flat seas.... And to think that 2 days before, on the way back from the last dive, my wife, while jumping from the Banka "at the wrong" time, sprained her ankle... It is therefore with a crutch that she will leave the Thalatta. Thanks to the carpenter, who quickly made him something to move around without putting too much strain on his foot. Thanks also to the masseuse who worked a miracle. Our physiotherapists should learn from this... More than an hour of massage to relieve pain and try to unravel problems and restore mobility. Back to diving. After the first day where we did a double dive trip to the south (Basak) and then in the afternoon a House Reef for the two of us, we left for Apo and three dives on the second. The crossing is slightly hectic but it goes well with the very comfortable banka. First dive on the bow of Apo.. hmmm but where have the fish gone? The place is still beautiful with soft corals everywhere, a few turtles but very few fish. The next 2 dives will be the same. Frustration, disappointment and sadness. After a little discussion, it seems that the locals are fishing in the "marine park"... Two days later the 2 bankas are scheduled for Apo... we will have a short day of rest. That's how much we were marked by this first outing in Apo. On the way back from the banka (yes there was only one that went out, the group that had booked the second one cancelled at the last minute ) those who dived there were delighted... obviously there was life... But it was the first time... or we had fallen on a very bad day. We will have to go back to find out for sure. A day doing nothing feels good but it's so long . We will continue by diving on the coast of Dauin to the north and south and for me a little "night dive" on the "House Reef"... and on the last day a single dive on the HR with a very sporty but then very sporty launch and return. The photographic harvest was less, as was the quality and variety of the subjects. It's nature, you have to know how to accept it. A small overview of the result. More here The Thalatta Resort, for those who know it, it's always the same. You feel good there, you should say: always so good. The restaurant is always good, as is the staff of the whole hotel who are very attentive, helpful and smiling. No regrets about coming back. The changes now: Alex, the new owner, obviously has plans not to change anything... i.e. to keep this family atmosphere. Keeping the same concept of what Patrick has built. But there is an important point, he intends to do better... To improve the Thalata little by little, in small steps and I don't doubt for a moment that he will succeed. He started by redoing the inflation installation New compressors, and nitrox per membrane... The best of the best, a very good start. On the hotel side, renovation work is being carried out everywhere. Small things like the restaurant toilets, the new fresco and different layouts tested. Everywhere, gardeners are replanting new plants to further embellish the setting. I like it. At the bar, installation of shade sails so that you can sit there during the day. I'm curious to see how it will evolve in a few months. Anyway, you can go quietly, you won't be disappointed, the Thalatta Resort is a place made for divers. If you stop by the Paris Dive Show, there should be a booth with the Thalatta. Alex should be there with the former owner Patrick. We will go there to say hello to them. There is a difference between Patrick and Alex.... Patrick didn't dive, Alex, yes and he's not a beginner.... I believe that there will be positive surprises in the future on the diving side. Small downside... As a child, the prices of the dives have increased slightly. After 2 stays of 10 and 8 nights I will not hesitate for a moment to go back but at another time when there is more life... why not spend Christmas 2025 there... the whole team is well on its way to make the atmosphere there, with the decoration and a nice "Christmas menu"... I almost placed an order . Let's move on to the 3rd part of our stay. Once again we made the choice to go back where we would be sure not to be disappointed. Yes, yes I know maybe we should go elsewhere to be more adventurous... Of course not. I totally assume this choice to return in order to enjoy even more and a little differently. We appreciate finding what we loved, in order to savor the place once again. If possible, we do a small combination of safe bets with "experimentation". The next trip will again be in this style 2/3 of novelty and to finish 1/3 back... But let's get back to this trip which ends in an hour with our landing in Zurich. Anda in the south-east of the island of Bohol is a remote place, it is the price to pay to find the calm... almost 3 hours drive from Tagbilaran without counting the 2 hour crossing by speedboat from Dumaguete. We will arrive at nightfall... very tired but happy to find the Island View Beachfront Resort that we had found magical the first time. Peter the owner has made small improvements such as terraces on the front of the cabanas bungalows. Sorry for posting all this pictures but it is such a lovely place. The restaurant, the "Old Plantation" is always at the top, the reference in Anda, and guests from other hotels come there to treat themselves. We had a great time... Too much maybe the scale won't like it, I'm afraid. After a visit to the room, we meet at the bar, Hubert the boss of Anda Scuba Diving whom we did not know yet since he was in France during our 1st visit. There is also Olivier who is in his third season here. Zack, with whom we had dived in 2022, has returned to France. Nice contact and appointment for the next day before 8 am for the paperwork and our first dive. After a restful night, we are at the club with "Captain Thomas" still in place, but now there is still Jason, a young Filipino, who takes care of the inflation and supports Thomas in all the preparations on the boat. He looks serious and during our stay he passed his Open Water. Hubert intends to train him to become a guide, and thus expand the team. The boat... It was replaced by a larger one but kept the same flat bottom philosophy in order to be able to sail in a few centimeters of water and be able to approach the beach at low tide. I find it really very good, comfortable, the edge is very wide, you are well seated and equipped with the block, it can be placed stable on it while waiting for the launch. The service is top-notch, and the security system is at the forefront. Only downside, yes I know I'm a born complainer there are only S80s.... But Hubert is well aware that it will be necessary to invest in some S100 in order to make heavy consumers feel comfortable and safe. I managed but I admit that I was a bit frustrated to often stay a little higher, just to keep the hour of diving... on the other hand I never used my reserve on fins which came out regularly with 100 bar... I let her enjoy her dives without playing parasite, attached to the rescue. Underwater, the same as elsewhere, less life and always the same reasons given. Not really the season, and in addition the water being particularly hot it seems to accentuate the phenomenon. In the end, the water lost 1 to 2 °C, going from 30 to sometimes 28 on the last day. There were quite a few turtles 2 years ago... But this year we have moved to a whole new level. There are many more of them and they are less shy. I think we are slowly approaching the "level" of Bunaken. Awesome. Unlike Dauin, we had a very calm sea being protected from the wind by the big island of Bohol. Very well. We enjoyed ourselves even if, as already said, I regret a little lack of life. But the last 2 days, there was starting to be a little more to see. According to Hubert, the high season is fast approaching, More to watch here On the diving side, as well as on the hotel and restaurant side, no regrets about having gone back to dive in Anda and as for the Thalatta I can only recommend the address. If the opportunity arises, we will return without the slightest hesitation. It's a good way to end a stay, with a little more upscale services. Depending on the return flight, it is necessary to leave a day earlier and spend a night not too far from the airport. This was our case. We made it simple by going to the Waterfront right next to the airport. Decent room, big and beautiful pool but on the restaurant side there is better. I regretted not having dinner while having a simple meal in the domestic flight airport lobby right in front of the hotel. In Singapore, the work is now complete. There weren't too many people I found, at least that's my impression. Singapore Air nothing to say, the economy class is not bad and when you see the comfort that those who fly in business class can have... I understand why this company is always so well ranked. Here we are back in Europe and tomorrow work resumes. The 7-hour time difference is really complicated on the way back, on the way there it goes very well. Who knows why Nice little trip of more than 3 weeks including the trips. But small frustrations due to a lack of life, yes, yes I'm jaded, there's no need to remind myself of that. Just like the weather which was not at the top of the best and which could have led to even more serious consequences for my partner's ankle. We were hot on this one. In the end, I dived a little less than expected with only 47 dives distributed like this: Maolboal: 11, Dauin: 16 and Anda: 20 On average, they had 1 hour, a maximum depth of 34m and only 3 dives of more than 30. A hiccup with a 38-minute dive because a member of the group was at 40 bar after 35 minutes of diving Now I'm going to get ready for the next trip which will be soon and to a mythical destination for divers, Raja Ampat with a short week in Lembeh on the way back, a destination just as famous for its Muck Dive. Thanks for reading. I publish the report in french and used the automatic translate module of Microsoft Word. I hope this stay comprehensible and you enjoy my report.

The night at Fakarava
9 pointsI planned for two days of diving in Fakarava; however, the airport fire fighters decided to go on strike while my wife and I were on the island. It did not take too long me to decide to do some more divings as I had to stay 6 extra nights at paradise. I'm actually glad I could've stayed longer... At one point, we were the only guests for days! Most divings at night were 1 to 1. The instructor and I tried something new other people had not done. I am also posting pictures on my instagram if anyone is interested in day divings as well. https://www.instagram.com/dive._.97/ However, night divings were highlight of the trip instead of the famous wall of shark. I am planning to go back in June to do some more night divings with sharks again.9 points

What Images Do You Keep???

- Preview of the MFO-2 - Now called MFO-3
I asked Nauticam to look into designing such a lens specifically because of the limitations of only having a one "decent" focal length macro lens on Sony FF (90mm) and Canon FF (100mm) camera systems. The MFO-2 basically converts the Canon 100mm into a 60mm macro and the Sony 90mm (or Tamron 90mm, I used today) into a 50mm lens - while keeping the fast AF (arguably helping it focus faster) and high quality optics of these popular lenses (and adding some water correction for good measure). These are simple test shots from toady. First a coral: left - 90mm alone, right - 90mm + MFO-2 - I am sharing screenshots straight from Lightroom without processing: Note it is hard to do an exact and exact comparison on real subjects because the MFO-2 requires refocusing. But it really makes a big difference to the field of view - I'd say at least the difference between the macro lenses many of us have spent years choosing between. Such shorter focal length macro lenses are very valuable for those that dive in poor visibility, for those that like some of the larger macro subjects (octopuses, frogfish, seahorses etc) and for blackwater photographers. And the lack of good options is a frustration. I made the request for this lens after my blackwater trip in March and it is exciting to see it already - I expected it to be more of a niche product for these specific users... I was surprised how long the lens is, which left me concerned it would be hard to aim and could unbalance the rig. The lens needs to be this size to perform well optically, but it is surprising lightweight for its size - and just a little negative underwater. However I was actually surprised that adding this lens makes the rig very comfortable and it feels very natural to shoot through it on a dive. Being noticeably wider than the standard macro lens it is actually even easier to aim and compose than the standard lens. I passed it to a friend during today's dive and he just got on with shooting it (I had to demand it back)! The image quality with the MFO-2 is very good. It is impressively sharp across the frame, with some mild CA creeping in at the corners. I'd like to test back to back to be sure, but I feel it is better in the corners than a Sony 50mm or Nikon 60mm behind a flat port, but behind how these lenses before behind a curved port. Anyway - it is very, very good. This shot shows corner frame detail at 100% on unprocessed RAW file (50MP camera) And here is another more central in frame - this time 200% zoom in on a 50MP file. It also focuses right to the front element - although like a port this starts to limit lighting options. Here is my finger (uncropped) to show smallest subjects it suits (same as 50/60mm on full frame, really). Now I have dived with it, its great strength is that it is light and easy to carry on all macro dives. Meaning that macro dives are no longer a decision between 105 or 60mm, you can now have both options, always. So when you see a great macro subject you can get two totally different macro shots of it very quickly. Before I used it underwater a serious M43 user (OM-1) on the trip asked me if he should order one. I said "No! You have the option of 4 macro focal lengths already, this isn't really for you." After the dive I said "Try it - if you do you will want one - it is so nice having the option of two macro primes with every subject." The MFO-2 is quite long - but this makes it light too - which makes it very comfortable to dive with and very natural to shoot with (contrary to what you might think with the length) - I really can't see me doing many macro dives without it. It was designed for FF Sony and Canon FF users frustrated with a lack of macro options. But others may be interested too, may turns to will if you get to try one. Hope this is helpful.8 points- My experience with the MFO-1
8 pointsI do think Nauticam's promotion of the MFO-1 has caused plenty of confusion around this lens, because they have drawn attention to minor features equally to its main purpose. I asked Nauticam to develop this product because I wanted a high quality, but weaker close up lens than the SMC. There are lots and lots of subjects that are a bit too small for a straight macro lens and too big for a SMC. The MFO was designed to plug this gap. The optical design of all of Nauticam's close up lenses includes a correction for the image aberrations created by using a flat port in water. This is beneficial for image quality (especially away from the middle of the frame) and also by presenting the lens with a clearer image - improves focusing performance of the lens a bit. The MFO also improves focusing because it stops the lens hunting as much because it makes it impossible to focus on very distant subjects in UW terms (as the focus range is now shifted closer) . This is particularly helpful with mirrorless cameras (PDAF) - which can struggle to know what to do when a subject is totally out of focus. That said, I would say AF improvement is a minor benefit of the MFO. Image quality improvement is also the same as other Nauticam close up lenses (they all aim to do the same correction for the flat port). I like Mike Bartick's comment on the MFO-1 in this regard - "think of it as a make it 'betterer' switch - stick it on your macro lens and just go and use it". The MFO will allow you to fill the frame with smaller subjects, stop you shooting things that are too far away, give small improvements in image quality and AF. The optical correction that all Nauticam's close up lenses make for the port is the reason it does not make sense to stack the MFO and SMC. As both perform a correction - you end up with a double change, in other words as far away from optimum as having no correction. So they work together, but without the image quality benefit. The other point I want to mention is that you should not ever use the Focus Limiter Switch on your macro lens whenever you might be using UW close up lenses. You need this full range of focus to properly exploit the full range of these lenses. I previously used the FIT +5 and the Nikon 5T for the role of the MFO. But these did not have the same image quality of the MFO, as they did not correct for the flat port aberrations (which is why I pushed Nauticam to make the MFO). I have shot the MFO for over a year (in pre-production form last year). It does not record in the EXIF, but there are 25 pages of images on my website since I started using the MFO and most of the macro shots are taken with it: see this page https://www.amustard.com/library/page/search/alex/26/ and forward to 1, which cover the last year (my most recent trip was sharks - so ignore the newest 90 or so images - pages 1-5!).8 points- Lightroom And Metadata for Underwater Images
Managing underwater photography collections can be overwhelming, but with Adobe Lightroom's robust metadata features, organization becomes seamless. On his blog, Mike Jones outlines a systematic approach to metadata management, emphasizing the importance of consistent practices to enhance searchability and gain deeper insights into marine environments. Key steps include: Rating: Assigning ratings to evaluate image quality. Keywords: Applying terms to describe the environment and subjects. Title: Using a consistent format for easy grouping. Species: Recording both common and scientific names. Category: Grouping similar species under broader classifications. GPS: Adding precise coordinates to document the exact location of each shot. Implementing these practices transforms your photo library into a valuable dataset, capturing snapshots of time, place, biodiversity, and behavior.

8 points- Help - strobe(s) not firing.
8 pointsEveryone take a bow. I went home amd went into that box of cables i never throw away, found a tos optical and gave it a snip and boom it works again. Returning the other set of cables i paid 100 euros for... Happy days.8 points- NEW strobe / videolight OPTIMA-10000 from Underwater Technics.
The strobes you listed are very worthy products. I don't discuss products from other manufacturers, it is not my task, sorry. I can only tell photographers about our own HSS system of the flash OPTIMA-10000 and about the essence of the HSS flash lighting in general. The principles of normal flash synchronization and HSS-flash synchronization are explained in the picture below: At slow shutter speeds (up to 1/250s) the normal usual synchronization is in effect - the flash fires once at the moment of the fully open mechanical shutter window, full energy flash usually lasts 1-2 milliseconds. This is called the normal flash synchronization, or "X-synchronization". But at ultra fast shutter speeds (faster than 1/250s) the shutter window no longer opens completely, such a moment does not exist at all, it is a narrow open strip moving along the frame during 5 milliseconds. Here only HSS synchronization is possible, - the strobe makes many small quickly following flashes (the base frequency is usually about 30 kHz) firing during 5 milliseconds, thus exposing the entire frame. And the faster the shutter speed, the narrower the open strip. The method of adjusting the intensity of HSS flash illumination usually is to change the frequency. The main problem with the HSS flash lighting is considered to be the so-called "Banding". These are alternating dark and light narrow stripes on the image. The reason is the parasitic interaction of the pulsations of the HSS flash and the camera shutter work. With an increase in shutter speed, banding increases, sometimes at speeds closer to 1/8000 it becomes unacceptable for shooting. Banding is very dependent on the camera and flash model. With one camera model it is more noticeable, with another less. The problem of banding at the global level in photographic equipment has not yet been solved, even in land photography. Manufacturers of photographic equipment are struggling with this effect, but with varying success. Our strobe OPTIMA-10000 has another HSS frequency and completely different method of HSS flash intensity adjustment, than other underwater strobes. It was our own development. Developing our OPTIMA-1000, we performed hundreds of experiments related to HSS, as a result of which we optimized the electronic components, parameters adjustments and firmware, related to the operation in HSS mode in order to minimize the banding effect. Currently, testing the HSS flash with the camera models we have in stock (7 camera models, including Nikon, Canon, Sony and Olympus), - there is no banding, the image is absolutely clear even at 1/8000. Of course, banding may appear with some other cameras that we do not have in stock, so we plan to gradually test all other cameras popular in underwater photography to confirm the effect. We will publish the results.8 points - Preview of the MFO-2 - Now called MFO-3
