If you have Facebook, maybe post this on the Tulamben community group? https://www.facebook.com/groups/172276879993151 - it's not as active as the Amed one, but you might be able to get an answer. Scuba Seraya's FB page hasn't been active since 2020, which is not a good sign, but there are recent google reviews, which is odd. Otherwise heard good things about Villa Markisa, Villa Utama, Tauch Terminal. cheers

Not the best of sources (Thaiger is a repost rag), but still interesting info https://thethaiger.com/news/national/parking-the-problem-thai-national-parks-close-to-revive-coral-reefs The Department of National Parks, Wildlife, and Plant Conservation (DNP) implemented indefinite closures at marine attractions in 12 national parks in Thailand to allow coral reefs to recover from bleaching. (...) To prevent further damage and allow for recovery, the DNP has closed marine attractions in 12 national parks until further notice. Human activity can disturb and hinder the coral’s recovery process. The closures affect the following national parks: Mu Koh Chang National Park (Trat) Khao Laem Ya-Samet National Park (Rayong) Khao Sam Roi Yot National Park (Prachuap Khiri Khan) Hat Wanakon National Park (Prachuap Khiri Khan) Mu Koh Chumphon National Park (Chumphon) Hat Khanom-Mu Koh Thalay Tai National Park (Nakhon Si Thammarat and Surat Thani) Mu Koh Surin National Park (Phang Nga) Sirinat National Park (Phuket) Ao Phang Nga National Park (Phang Nga) Than Bok Khorani National Park (Krabi) Nopparat Thara-Mu Koh Phi Phi National Park (Krabi) Mu Koh Lanta National Park (Krabi) Three additional locations are under special surveillance due to severe coral bleaching including: Koh Jan in the Hat Wanakon National Park in Prachuap Kiri Khan Koh Pling in Sirinat National Park in Phuket Mu Koh Chumphon National Park in Chumphon Koh Khram Koh Ngam Noi Koh Ngam Yai See also: https://thethaiger.com/news/national/coral-catastrophe-strikes-krabis-mu-ko-lanta-marine-park Phang Nga's Similan Islands NMP, badly hit in the 2010 bleaching event (some famous sites, like East of Eden, are closed to this day for "recovery and monitoring"). has already entered its yearly closure period.

Aaaah, compacts 😍 - Maybe we should start a retro trend and shoot uw video on VHS-C and Hi-8 camcorders? (digitalised to 4K, of course) Woah, look at the rad overlay and generation-loss on that reef fly-by!

On my macro video compact rig, I started out super negative (-1.5kg) but are now currently only a little negative. That said, I use a quadripod, not a tripod, and the rig is really stable, even when close to being neutrally buoyant. Buoyancy varies with the diopters I use (Inon UCL165, AOI-09, CMC-1 or stacked combinations of these), but I love it like this. When i started out really negative, the legs would dig deep into the fine vocanic sand we have here in east Bali, and stir up clouds even if I only nugdged the camera alittle to reposition/focus, or when lifting the quadripod off the substrate, no way around it, even when going very slow and easy... Not fun... It was also tiring to carry underwater on the extended shallow dives I do here, and made a big difference in my own buoyancy when I no longer held the camera, not really pleasant having to adjust all the time. I started adding floats (my wide angle rig is neutral) and found out that it doesn't affect shot stability with my quadripod. Another positive I can also now do handheld shots, or semi-handheld using only two legs (which opens up tilt camera movements for instance). I actually tested neutrally buoyant macro dive a couple of days ago, trying a new float setup based on the Wolf - So two big top mounted floats setup in a triangle. Camera was even a tiny bit positive without the diopters (I use 3, and have them on me rather than on a flip mount), but was nice and comfy neutral starting with my smallest Inon diopter, to slightly negative with the others. However the Wolf based setup was cumbersome, and I didn't like having the buoyancy compensation so high up which kind of pulls up the rig, and makes trim/buoyancy adjustements difficult, so i went back to my former setup (main floats compensating 1.1 kg horizontal across the rig, then two float arms vertically in the middle holding on my main macro light, a Backscatter MW4300). I can adjust buoyancy distribution / trim with the back float horizontal float. It's cable-tied to the main horizontal float which can pivot around it, so I can easily move buoyancy closed to the front of the rig (good for front heavy lens stacks). A picture might make more sense: i think using a quadripod really helps for video, allowing us to work really only slightly (100g or so) negative - of course any strong surge or current would affect the rig more than a heavier one, but I find it also affects smaller macro / super macro subjects so much that it's very difficult to get usuable footage anyway, as they swing in an out of focus too much, so it's not much of an issue. And making it lighter really helps with camera repositioning, semi-handheld and full-handheld shots. cheers ben

Thanks a bunch Matan! Yes, despite a limited focal range (compared to newer RX100vii with it's massive 200mm zoom lens), macro capacities are really good on the LX10 - with a good set of diopters, that is. It's a fixed lens on the LX10 so i'm just adding diopters based on the shot - I have a +6 Inon UCL165, an AOI-09 +12.5, and at the time I shot this clip I was still using an +10 diopter made for GoPro (Backscatter's macro mate mini). I've sold this since and managed to buy a second-hand Nauticam CMC-1, which is roughly a +15 diopter, so quite close to the AOI +12.5. Conditions here in east Bali have been bad the past couple of months with rainy season, so I haven't been shooting as much as before - but it's clearing up now, even though subject wise it's still not back to what it was, so I'll be working with the new lens. Based on the tests I did do, my working combinations are the Inon on it's own (bigger subjects, wider shots), CMC-1 on its own (lovely), and CMC-1 stacked with the Inon. For tiny supermacro sujects, I also use CMC-1 stacked with the AOI09, which is a really good combo (even though I would have liked to have a more powerful single diopter to have a shorter lens, which allows to get closer and avoids losing light - alas they're very expensive (I had my eyes on the AOI 900 Pro +23, but it's not in the books. So i'm keeping the AOI-09 for now, as it opens up stack possibilities for very small subjects, even though i no longer use it on it's own, and use the CMC-1 instead. They're very close, but the CMC-1 is a little shorter and brighter, and thus offers a tiny bit more magnification. But when stacking the AOI-09 and the CMC-1, the depth of field is really tiny, so the subject has to be very stable... Any swaying or movement of the animal and it will be violently swinging out of focus, - this is a little different from macro photographt where you just need to freeze the subject in focus. For video you want at least 10 seconds in focus, ideally more. So swell and current makes it difficult to get usable supermacro video subject. I've also managed to shoot a triple stack, which works only in the following order: Inon, CMC-1, AOI, so the weakest diopter first, which is most likely due to lens design curvature. In a more classical strongest diopter first order (CMC-1, AOI, Inon) it focuses on the glass.... But it's difficult to use, and only for very stable tiny subjects... cheers ben

Wow - I didn't know these existed - I've found a DC coupler (dummy battery) for the LX10 (link) - could this be used with an external battery pack to power the compact? Anything giving more battery life underwater would be fantastic. When you were working with the RX100 series, what external battery pack were you using, and how did it compare to standard batteries when shooting video? Thanks! Ben

Great thanks you Tino. Unfortunately I think it's a no-go - the NA-LX10 only has one M14 port, used by the vaccum valve. Not sure what the flash socket is - I do have unused optical fibre holes.

Hi Tino - and wow! I'm very interested in this underwater-powerpack, as battery life is not good on my compact (LX10), with which I shoot video - the camera can work powered by a slave battery, but there's no room in the housing. Did you make this work with the RX100 Nauticam housing? if so, how did you get the cable in? I only have on bulkhead port used for the vaccum valve, but do not use any flash - no idea how these ports work however. If you have the time, a little photo write-up in the DIY section would be great. Cheers ben

Mine uses the CR2032, and I turn the vaccum detector on the afternoon/evening before the diving day, turning it of in the afternoon the next day (so it's on roughly 24 hours). Diving usually 3 times a week, batteries last roughly 2 months before I start to see some sort of low battery indicator flashes, but this is Indonesia so they might not be the best, and environmental conditions might also be at play. I was using Panasonics with expiry date in 2030, but switched to Energizers which seem to hold a little better.

I'm not sure if this belongs here yet, but someone contacted me through my Youtube account email enquiring about the Lumix LX10 I'm selling on Mozaik. Well, while i do shoot an LX10, I'm not selling any at the moment, so I asked details about about the ad he mentioned. it turns out a vendor has put an ad for an LX10 kit on Mozaik, and linked to one of my YT vids shot on the LX10 - which is fine, however I'm a little confused by the wording, which reads: "Example of videos shot using this camera (and to give you confidence in buying from me):" Confidence in buying from me - while listing someone else's vids? Errr, wait? So the second YT link is to my ambient light LX10 test shot vid shot mostly while I was working in Palau - the first link is to video made by by someone else, but shot in the Similans NP in Thailand (where I did work a few years back...). I told the person who contacted me by email to be very careful, and also flagged it with Mozaik, but haven't had an answer yet. Another potential red flag is that the camera model given in the specs is OM-1, but this could be a template issue? I would say it's either very clumsy, or a scam. The ad is here: https://www.housingcamera.com/used-panasonic-lumix-lx10-digital-camera-nauticam-underwater-housing-pro-package-accessories.html Beware...

Hi and welcome Andi - what is your research focus in FP? ben

This database might be of interest to some of you. It's a detailed database tracking production and emission specs of 122 of the world's largest producers. https://carbonmajors.org/ Detailled open-source data is available for download here : https://carbonmajors.org/Downloads and a presentation of the methodology used is accessible here: https://carbonmajors.org/Methodology Fron the site description: "Carbon Majors is a database of historical production data from 122 of the world’s largest oil, gas, coal, and cement producers. This data is used to quantify the direct operational emissions and emissions from the combustion of marketed products that can be attributed to these entities. These entities include: 75 Investor-owned Companies, 36 State-owned Companies, 11 Nation States, 82 Oil Producing Entities, 81 Gas Entities, 49 Coal Entities, 6 Cement Entities. The data spans back to 1854 and contains over 1.42 trillion tonnes of CO2e covering 72% of global fossil fuel and cement emissions since the start of the Industrial Revolution in 1751." Analysis of this data set, such as this one here, highlights the fact that a mere 57 entities are linked to 80% of global emissions since 2016. b

Looks fantastic, thanks for sharing this great piece of DIY!

A few Andaman Sea liiveaboard boats that used to go to from Thailand up to Myanmar/Burma (leaving from Phuket or Khao-Lak/Tap Lamu or Ranong used to organize blackwater dives - my wife did one on a trip to Myanmar on a trip she worked the Andaman Queen, and otherwise the Smiling Seahorse used to do regularly them as well. I doubt the trips are running with the ongoing situation in Myanmar, so not sure what the blackwater status is. Maybe it's possible to do blackwater on the Thai side, in the Similans/Surin islands, but it's fairly shallow, and night diving itself really wasn't a highlight when I was working there...

Various types of Shaun the Sheep / Costasiellidae nudis are found in the Tulamben area as well, it's actually one of the more common nudis out here. I'm sure Ajiex will have no problems finding them for you, and probably lots of other, rare nudis. It is seasonal, but the Shaun the Sheeps are year round 🙂

Unfortunately not for west Bali / Permuteran and Menjangan... My mandarin-fish data is pretty limited... other than Bunaken mentioned above, we did have mandarin fish for a while under staghorn coral in Siaba Besar (central Komodo) when I was working there, and more recently loads of very easy to spot mandarin fish in Palau (just outside Chandelier Cave, in 5m of water, way more than in the so-called "Mandarin Fish Lake"). Won't be much help for Bali though...

On the other hand, you do have places like French Polynesia (Rangiroa, Fakkarava) or even Palau (reef sharks for the most part, but also bullsharks and oceanic black tips on the spawning dives, and the odd tiger at German Channel), where sharks baiting is illegal, yet where sharks (and related dive tourism) play a major part in the local economy. Same goes for the hammerhead schools and sharks in the Eastern Pacific or the Banda Sea for instance, that attract a lot of divers to see sharks in unbaited, more pelagic settings, or even the (slightly iffy atm) oceanic white-tips and other sharks encounters of southern Red Sea itineraries, where shark expeditions are run quite regularly. In the end, it really depends on the type of sharks you want/expect to see - baiting focuses on attracting mostly larger, more pelagic species that are more difficult to see in a non-baited context (with a special focus tiger sharks and bullsharks, great hammerhead or even great whites for the now banned Isla Mujeres operations etc). As a slight counterexample to this "fundamental economic principles", there are Marine Protected Areas - these can do a lot for rebuilding the ecosystem, and while enforcement of the MPA can be an issue, they probably do more good than baited diving operators do, especially on the long term. The Misool Eco Resort in Raja Ampat was built on what was primarily a shark-finning camp, and shark populations did rebound after the establishment of the MPAs - sure, we're talking reef shark here, but this does not mean there aren't bigger pelagic sharks around. However, you will probably not see them. This is normal - the bigger, pelagic sharks which are the stars and highlights of chummed-dives are actually around in quite a few diving areas that do not practice such baited/chummed shark dives. If you could bait/chum in Palau, you would surely get all the bigger sharks as well - fishers or people looking for whales on the outer reefs see silkies, tigers, great hammerhead, bulls, oceanic white tips and black tips - they're definitely around. But just not on the main dive sites. Same goes in many diving areas, even Bali's Lombok strait, off the macro-focused Tulamben area actually has its share of big sharks, fishers on rumpon fish aggregating devices see tigers, hammerheads and more - a random great hammerhead showed up on a Tulamben dive site last month. They're around, and baiting/chumming would most likely work, for instance, even in a place where (now illegal) shark-finning is still a major, ongoing issue. Bigger sharks play their role in the ecosystem, but are not generally seen by divers, for behavioural and habitat reasons. I hear the conservation argument (basically: if it wasn't for the chummed shark dives locals would be shark fishing/finning), and I'm also with you in that it's not for me. As for the only protect what we know, can experience and love idiom, we need to remember also very good at commodifying natural highlights, and in a bigger picture, the impact of such a commodification of ressources can also be quite high, and the conservation argument can easily turn into some sort of self-justifying greenwashing. Seaworlds and similar venues have long used the educational agreement to justify their debatable practices, such as the captivity of large marine mammals, for instance. Sure, shark chumming is not the same thing, but even if the animals are not less fascinating when they have been baited, divers have to keep in mind that they are taking part in an artifical animal-encounter activity which is repeated daily, sometimes multiple times a day, with a definite impact on animal behaviour. As often, the frequency of the event is key - same goes for touching marine fauna and flora, fish feeding - the impact of such micro-events might be relatively small, but exponentially amplified if repeated daily on a large scale. Practically, when I see behind-the-scene footage of divers kneeling in front of the chum buckets waiting to take pictures in Fiji or the Bahamas (or the "shark scramble" in Japan's Chiba prefecture...), I know deep down this is not an experience I would want to be a part of, regardless of how cool the end footage would be. Even more "open water" settings like blue shark dives in the Azores or shark dives off Cabo San Lucas are not super appealing to me to be honest... I get it, but don't really want to do this. I would much rather pay to try to see a few seconds of a baitball in Bahia Magdalena for instance, or cross-finger to hammerheads in Alor or the El Bajo in the Sea of Cortez (to give a sad example of dwindling shark populations, primarily due to poor handling of the shark breeding area...). But then again I'm not a fan of zoos and aquariums as well, and consider that when it comes to animals and fauna spotting, diving is (and should remain) more a gamble than a fully-marketable, bang-for-your-buck experience. I personally hit my limit when I was working in the sea of Cortez and doing California sea lion dives daily. Sure, it was taking divers to a sea lion colony (rather than artifically attracting them), but it started to feel like I was working in a zoo, and that made me increasingly uncomfortable, and realise that this was not really the kind of diving experience I was interested in facilitating, regardless of how fantastic the sea lions are (they are!). Returning to shark dives, (so-far) more "unintentionally chummed" (tuna fishery) tiger dives in the Maldive's Fuvahmulah sound a bit more fluid, as it's taking advantage (again, for now) of an existing man-made situation. I think the bull-shark dives in Cabo Pulmo are similar. Same goes for observing mantas at cleaning stations, which, if done reasonably, doesn't really have the same impact as light-pooling (plankton aggregating) operations for instance. As with most conservation issues, it is far from black-and-white, good/bad, but chummed dives are taking the diving experience in a direction that I'm personally not interested in - again, regardless of how amazing the resulting footage of animals that would not be encountered otherwise would be - and find that the conservation argument is also somewhat debatable.

Found this source in France: https://www.plongimage.com/lentille-macro-ucl-g100-sd-inon-pour-gopro.html https://www.plongimage.com/lentille-macro-ucl-g55-sd-inon-pour-gopro-1.html Otherwise I would get in touch with Photodenfert, they do sell Inon lenses and can probably place an order for you: https://www.photo-denfert.com/ cheers b

cool! the manta pics at the end are in Maamigili right (South Ari atoll, island with an airport)? I've guided there many times when I was working there and the table corals to the slope are quite remarkable. Apparently the site was rubble only a few years back, and now the table corals are (almost) all over the place. It's also a shark cleaning station, got silver tips a few times, bigger than the usual grey reefs!

Wow, really great footage indeed from Team River there! The AOI lens is definitely on the wtb list, when I'll update the action cams. Do you think it could it could be made to fit on the dive housing of the other action cam contender's nsta 360 Ace, or would that be asking for trouble?

Argh - post swallowed by the forum.... retype... Indeed, indeed... I was thinking on inside the actual lens, which might not really be visible from the outside. Weight pulling on the cover, changing exposure to temp, something like that.... Is it a new issue with the waterproofing? I've snorkeled many times with the GoPro7 without the protective lens cover, never had issues. You need to remove the protective lens cover to use the dive housing, so I just got rid of it altogether. If it hasn't changed too much, the lens was actually screwed in, and goes quite deep inside the cam. I changed the lens of my useless GoPro6 for a 3rd party non- distortion 3.37mm lens, and was worried about loss of waterproofing. But when you unscrew the GoPro lens (don't do it, you will need to adjust focus manually afterwards which is tricky), you realise it's quite sturdy. On the previous models (up to the 7), this is what the actual lens looks like bare: (great little product this btw, a 3.37mm non distortion lens by Mapir / Peau Production, good stuff : https://www.peauproductions.com/collections/gopro-hero-7-6-5-cameras-and-lenses/products/3-37mm-f-2-8-87d-hfov-16mp-br-no-distortion-hero-5-6-7?variant=39863341285463 )

I see I see. Very mysterious, this fogging issue. If it's only with the AOI then the only further speculation I can offer would be that the weight of the lens is pulling on the protective lens cover as you'd already figured out, and this is still happening, over time during the shoot, despite all the care taken on setup. Maybe this is generating a greater temperature differences with the lens somehow, and generating fogging inside the lens. One way to test this crackpot theory would be to remove the protective lens cover on one of the other gopro to see if this generates fogging as well no warp-free pans and fly-bys on the gopro then eh... Good chance the lens helps a bit though, we'll see!

That is very nice indee, crisper and sharper ❤️ I know you're shooting on a tripod at a fixed angle here, but really looking forward to seeing some pans and camera motion with the new lens config, as this was where the GoPro angle warping was/is generally really bad Your blur issue is odd indeed - could it be an internal lens condensation issue because of the temperature difference between the cam and the environment when shooting for extended durations?

Out of curiosity, would anyone know what cinema camera is it seems to be mounted on here? Housing looks like a RED Digital Cinema V-Raptor housing - not sure if the lens here is the FCP-1 (or is that the WACP-2?), but if it is indeed, I would love to see some video footage shot with this combo!
