Aquatica Glass Dome Polishing Exterior Haze / Water Spots
I don't know of any domes which are coated on the outside, it would be attacked far too easily.

Aquatica Glass Dome Polishing Exterior Haze / Water Spots
If the cerium oxide works it will remove the coating applied to the glass from factory, I assume? Does the factory coating really even matter optically? I know some domes don't even have coatings or only an internal coating.

Aquatica Glass Dome Polishing Exterior Haze / Water Spots
I now blow the water droplets off my port, I purchased a mini blower designed for computer equipment and similar and it blows the droplets off, follow by a soft microfibre cloth to leave the surface clean and bright. The slats concentrate up as the water evaporates and particularly if the salts in the water are alkaline the can etch glass. By all means try out the cerium oxide, but if that does not work, I have heard the costs for new glass are not that high.

Aquatica Glass Dome Polishing Exterior Haze / Water Spots
Roger, I did do some searching but couldn't find anyone that was able to solve it, lol. I tried the 50/50 water/vinegar and that didn't work. Coke is an interesting one, might try that! I am getting some cerium oxide powder tomorrow so will give that a try.

Aquatica Glass Dome Polishing Exterior Haze / Water Spots
There’s been loads of posts on this issue. Definitely worth a search. Some options; 50/50 solution white vinegar and water Coke Mothers windscreen cleaner Brasso Cerium Oxide powder (as Dave suggests) Good luck with them. My own experience is that once the film has been on for a while it’s extremely difficult to shift it. Re-glassing has been my experience. With new ports now, I follow the Chris Ross routine: good soak and do not let the ports (and viewfinder optics) air dry. Wipe them dry with microfibre cloth as they come out the rinse tank.

Aquatica Glass Dome Polishing Exterior Haze / Water Spots
Yes, I need to make a dunk tank with some distilled water for sure. The well water doesn't help.

And get yourself a supply of distilled water for soaking your camera. That hard well water is depositing minerals like calcium which is causing the spots on your glass.

Rectilinear WA - Nikon Z8 - What's "best" optically?
@Phil Rudin In your experience: Would the Laowa work "better" behind a 230mm dome? What have you found extension length to best be? 40mm or 50mm? Sounding like a great replacement for the Sigma 15 FE that I just sold off as it requires external motor...

Aquatica Glass Dome Polishing Exterior Haze / Water Spots
Hello, I have a very cloudy exterior film on my Aquatica glass megadome. Possibly salt etching? or the exterior coating is done? Most of the time you cannot see it in my video when underwater, especially when using my lights but when trying to film ambient or at the higher base ISO of my camera (12800) it's very noticeable. Any ideas on how to correct this? I have a couple trips coming up this next week, but after I am back I may just send it to Aquatica to have new glass put in. This dome is only 2 years old. I did try a claybar for auto detailing, that did nothing. I've tried vinegar/water that also did nothing. I have ordered some cerium oxide powder and will try that. I know Aquatica uses BK-7 mineral glass but I am unsure if they have an external coating on the dome. I did some searching but couldn't find a solid "how to" to repair this. I do rinse my gear after every dive but my rinse water is from my well, so this may be an issue too. Thoughts?

Talk to me about the Canon R50, please
Hi @Kristin this is taken with the nauticam housing using the kit lens. To build on Chris' comments about swapping between macro vs wide, I'm not swapping on the same dive but just deciding beforehand. FYI the Rhinopia shop was taken on the WWL1 but zoomed in so just goes to show what can be achieved! I also experimented with someones CMC-1 but preferred the dual UCL 165s for flexibility, plus they cost less.

Glad to say I’ve never come across anything like this. Bizarre to say the least. The potential charge was outrageous.

Matthias Lebo Demonstration Dive Light Test 18.000L VS 5.000L (Keldan, Divevolk, Seafrogs)
The Keldan used is a actually an ambient-light model, so the colour temperature is shifted in the light itself to emulate what you would get when using an ambient-light filter, but without the loss of power caused by the filter, usually around 1.5 to 3 stops depending on the filter. Great for mixed lighting, but limiting for macro/night diving applications for instance. And not sure it would work well in the Med's greener water for instance Meh... The test would have been more useful if it had measured the amount of light actually falling on the subject, using a fixed camera exposure. He could then have measured the exposure adjustment required to bring the scene to the same level with different lights. The waveform of the pool wall doesn't really tell us much. Lux or candela measurements would also have been very useful of course, but require equipment. Other aspects worth testing would be beam angle and edge sharpness, whether the light maintains constant output or dims as it discharge (mean the lumen output is not constant), light runtime at full power for instance. Super important data, and easily measureable in a pool. Then there's the question of durability of both the light and the battery pack, which is probably the hardest data point to measure, as it requires actual feedback from actual heavy users. Alex Lindbloom once wrote an article about his 1,000-dive test of his Solas and other brands, which he was using daily while working on a liveaboard. That kind of real-world data is gold.

Advice on a Carry-On Camera Backpack
Yes - there is also something called the main carrier rule for tickets bought through one company, but that codeshare with another one for a section of the trip. Up to now, I'd never had an issue. The initial baggage allowance was kept throughout the flight, or in some cases actually increased to the level of the flight providing the highest allowance in the trip (e.g. a La Paz-Mexico City-LA-Tokyo flight on Aeromexico, where the luggage allowance for the whole ticket was based on the LA-Tokyo flight, hence more generous than it would have been on the La Paz-Mexico City-LA leg...) I'd never had it reduced like on this JAL flight from Tokyo to Male, with the return flight applying Malaysian Airlines' rules on the Male to KL section only (since we didn't have any issues on the KL to Male section)... This was a return flight fully booked on JAL, the longest leg of the trip was on JAL, so normally main carrier rules. But nope, not always... Yes, but keep in mind that I'm talking about a single flight here - we didn't buy multiple flights, and it wasn't multi-city - it was a single Japan Airlines return flight from Tokyo to Male and back, bought directly through JAL. However, it transited through Kuala Lumpur, and the KL-Male-KL leg was codeshared with Malaysian Airlines. Given that this was bought as a single JAL flight, and that the longest leg of the trip was on JAL, normally this is where the main carrier rule applies (as it did on the outbound leg). But not always, as we discovered... the luggage allowance on this single JAL flight went: Outbound check-in: Tokyo > Kuala Lumpur : JAL luggage allowance Kuala Lumpur > Male: JAL luggage allowance Return check-in: Male > Kuala Lumpur : Malaysian airlines luggage allowance Kuala Lumpur - Tokyo : JAL luggage allowance

Matthias Lebo Demonstration Dive Light Test 18.000L VS 5.000L (Keldan, Divevolk, Seafrogs)
This is a marketing demo, not a real tech comparison, so nothing interesting. BTW I like Keldan's blueish color. It should give more balanced look.

Matthias Lebo Demonstration Dive Light Test 18.000L VS 5.000L (Keldan, Divevolk, Seafrogs)
Even if he used a fixed exposure camera to film the test (and I think he did) He demonstrated nothing except (maybe) that the declared Lumen output is more or less correct. Completely useless.

Cozumel Officials Clarify Customs Treatment of Dive Computers and Underwater Camera Housings
Underwater camera housings traveling with their corresponding cameras are to be treated as photographic accessories, while dive computers are to be classified as sporting equipment, according to Cozumel tourism officials following meetings with Mexican Customs. Broader questions about strobes, ports, wet lenses and whether the interpretation applies throughout Mexico remain unresolved. September 21, 2026 — WaterPixels There may finally be some movement in the long-running dispute over how Mexican Customs treats the specialized equipment carried by visiting divers and underwater photographers. Following meetings between Mexican Customs officials, the Quintana Roo Tourism Secretariat (SEDETUR) and representatives of the diving industry, Cozumel tourism officials say two particularly important pieces of equipment now have clearer treatment when visitors enter the destination: dive computers and underwater camera housings. According to Elías Farah Ceh, Cozumel's Director of Tourism and Economic Development, dive computers brought by tourists are to be classified as sporting equipment rather than laptops or tablets during Customs inspections. For underwater photographers, an even more significant clarification concerns camera housings. Farah Ceh said that underwater camera housings will be considered camera accessories when they travel with the corresponding camera. If a housing is transported separately from its camera, however, it may instead be counted against the passenger's duty-free merchandise allowance and could become subject to tax if the applicable allowance is exceeded. The clarification was reported September 19 by Mexican news outlet Ruptura 360, following a meeting in Cancún involving Customs personnel, SEDETUR and representatives of Cozumel's diving community. Customs shown how modern dive equipment is actually usedThe issue appears to have gone beyond a conventional meeting between government and tourism officials. During the discussions, experienced diver Alberto Friscione reportedly demonstrated equipment used for both ocean and cave diving, helping Customs personnel distinguish specialized dive equipment from ordinary consumer electronics. That distinction is particularly relevant to dive computers. Although today's units may resemble sophisticated smartwatches or electronic devices, their primary function is as life-support-related diving instrumentation, tracking information such as depth, dive time, decompression status and other parameters needed during a dive. Treating such a device as a laptop or tablet can therefore create problems when Customs officers apply passenger allowances intended for conventional electronics. The same problem has affected underwater photography equipment. To someone familiar with underwater imaging, a camera housing is clearly part of the system required to operate a camera underwater. But Mexico's published passenger-baggage rules refer more generally to cameras and “photographic material,” leaving considerable room for interpretation when Customs encounters housings, ports, strobes and other specialized components. The latest Cozumel clarification appears to address at least the housing portion of that problem. Quintana Roo confirms underwater photography equipment is being discussedThe Government of Quintana Roo has separately confirmed that underwater imaging equipment is part of the current discussions with Customs. In a September 18 statement, SEDETUR said representatives met with Cancún Customs officials and members of the nautical and diving sectors specifically to review the equipment now being brought into the Mexican Caribbean by visiting divers. That review included equipment used for cave and cavern exploration as well as specialized underwater photography and video equipment. Cancún Customs chief General Luis Antonio Balcázar Bustos participated in the meeting along with senior officials responsible for legal affairs, passenger services and Customs operations. According to SEDETUR, the meetings are intended to produce several improvements: better training for Customs personnel; direct communication between Customs authorities and representatives of the diving sector; and clearer information for tourists arriving with specialized equipment. Additional Mexican reporting published September 21 says those efforts are continuing as officials work to establish procedures that make entry into the Mexican Caribbean with personal and specialized diving equipment more predictable. SEDETUR Secretary Bernardo Cueto Riestra said more than half a million tourists visit the Mexican Caribbean annually to dive, making resolution of these issues particularly important to the region's tourism industry. Complaints and cancellations put pressure on officialsThe discussions follow a period of increasing frustration among international divers and underwater photographers. WaterPixels has followed reports involving Customs treatment of underwater imaging equipment in Mexico since 2024, including complaints associated with Cancún, Cozumel and Los Cabos. More recently, local Cozumel business representatives have said uncertainty and disputed Customs charges have contributed to cancellations by visiting dive groups. The issue gained additional attention this summer as individual divers and underwater photographers began publicly calling for travelers to avoid Mexican dive destinations until the Customs situation was clarified. The current discussions between Customs, tourism officials and the dive industry appear to be a direct attempt to reduce that uncertainty. Important questions remainThe latest development is encouraging, but underwater photographers should be careful not to interpret it as a complete resolution of the Mexican Customs issue. WaterPixels has not yet located a published national directive from Mexico's National Customs Agency (ANAM) formally stating that the camera-housing interpretation applies at every Mexican port of entry. The current information comes from Cozumel tourism officials describing agreements reached during discussions with Customs. It also addresses only part of a typical underwater imaging system. Questions remain concerning equipment including: dome and flat ports; interchangeable lenses; underwater strobes; video and focus lights; wet wide-angle and macro lenses; external viewfinders; extension rings and gears; strobe arms and related accessories. A serious underwater photography system can contain all of these components while still involving only one personal camera. How Mexican Customs classifies that complete system remains the key question for traveling photographers. There is also an important geographic question. Are these interpretations being used only in Cozumel and Cancún, or will Customs officers apply the same criteria in other Mexican entry points, including Los Cabos? Until that question is answered by ANAM or another federal authority, travelers should not assume that procedures will necessarily be identical throughout Mexico. WaterPixels has requested official clarificationWaterPixels has sent a detailed bilingual media inquiry to Quintana Roo Tourism Secretary Bernardo Cueto Riestra and Cancún Customs, asking for clarification directly from the authorities involved. Among the questions we have asked: whether a camera housing traveling with its camera is officially considered part of the personal photographic system; how ports, strobes, lenses, wet optics, lights and other underwater imaging accessories should be classified; whether limits exist on the number or value of those accessories; whether these interpretations apply nationally; what procedure travelers can use to challenge an assessment they believe was made incorrectly; whether an ATA Carnet is expected for recreational photographers; and when the proposed clearer equipment guidance will be published. We have also asked officials to clarify the status of the temporary Customs arrangements reported earlier this summer and reports of new complaints after September 1. At the time of publication, WaterPixels had not yet received a response. For now, the recognition that an underwater housing accompanying its camera should be treated as a camera accessory, and that a dive computer should be treated as sporting equipment, represents a potentially meaningful step toward resolving the problem. The larger question is whether those interpretations will now become clear, written and consistently applied Customs policy across Mexico. This report is based on official statements from the Government of Quintana Roo and SEDETUR, recent Mexican news coverage, and documented reports from the WaterPixels community. WaterPixels has requested additional clarification from SEDETUR and Cancún Customs and will update this story as new official information becomes available.

Found: Dive Computer
I know, not explicitly photography related, but thought I'd give this a shot. Found a decent dive computer in Galapagos recently. If anyone knows anyone who may have lost one, DM me with some details on where it was lost and computer details. Jim
