PVC Foam Floats
Last year, I managed to get samples of 80 kg/m³ and 100 kg/m³ density PVC foam, rated to reliably withstand pressures of 0.6 MPa. They work great, but sourcing this type of material in Japan was a nightmare (mine eventually came from Chinese manufacturers instead, and that was not easy). I gave up on fishing floats, as it was impossible to find proper technical specifications locally. I spent a lot of time searching on AliExpress and Alibaba, but without success. I tried shipyards and marine supplies, no luck. Given the value of this kind of material for underwater imaging applications, it would be great to share supplier information, especially from companies willing to ship non-industrial quantities internationally. Given the links above, it seems to be easier to source in the EU somehow.

PVC Foam Floats
It Depends, the float collars for WWL are polystyrene but are high density version of foam. Some average polystyrene you find in a craft store likely would not be as strong.

Methods to determine lens to dome port distance? (I hope that makes sense!)
Since its been covered extensively in the links above and various threads, no need to repeat the process description. Probably quickest to spell out the particular lens / camera / housing / dome combo you are interested in, and ask if anyone is using / can advise on how it goes. There are many possible 'off piste' (off port chart) rigs, some of which work very well... and some which don't!

PACKING ADVICE AIR TAHITI
Hey everyone, I'm travelling to French Polynesia (Tahiti, Moorea, Rangiroa and Fakarava) in two weeks and was hoping to get some advice from anyone who's flown with Air Tahiti. Their carry-on policy says the limit is 5 kg, which doesn't leave much room for camera gear. I'm travelling with a Nauticam housing for a Sony A7R VI, along with a WACP-C, and I normally carry everything in a Wandrd Hexad Access Duffel backpack as my carry-on. I've never had any issues with major airlines or other regional carriers, but I know Air Tahiti operates smaller aircraft and I'm a bit concerned about how strictly they enforce the carry-on weight limit. Has anyone travelled with underwater camera equipment on Air Tahiti? Were they strict about the 5 kg limit, or did they mainly care about the size of the bag? I'd really prefer not to check my camera gear if I can avoid it.2 I'd really appreciate hearing about your experiences or any tips. Thanks!

List of Available Strobes
Backscatter has some innovative strobes since that list that have ttl for om system and somy. I switched from Inon 330 to their Hybrid Flash. They came out with anAtom flash in the past year or so too. All with accessories available like snooting and color filters. Recommend checking them out. Hybrid can serve as a strobe and a video light on the same dive.

Mexico Underwater Camera "Tax" spread to Cancun
Ridiculous. This Bernardo Cueto Riestra is either too lazy to grasp the issue and why it is unreasonable, or he just don’t care—which is his job as the secretary of tourism. I cancelled a WS in Socorro earlier this year and went to the Maldives instead to shoot sharks.

Monitors with really long battery life?
Ability to watch movies would be a plus when doing my archaeological dives - over 2 hours of deco!

Monitors with really long battery life?
For this use case I would probably skip on Weefine and go for Shinobi in Nauticam housing with NPF-950 battery. I will last whole day with time to spare. So although I was recommending Weefine in the other thread now with this use case on hand I would advise against and go with Shinobi. You may even watch movies on extended deco stops 🤣 Another plus for Shinobi is its neutral buoyancy.

OK it might be worth a try then. Hopefully 12degC water won't affect the battery life too much.

Sony FX5 released
Can't speak for other models but Sony A1 CWB is great even at 30m depth. Official metadata say like WB >9900 but Lightroom often displays WB at above 15000K. CWB at depth is what is going to remain to be seen on FX5. Unlike other models with square pointing at white target FX5 calculates CWB from the entire frame (!) pretty much like Canon was evaluating the picture in the past. I haven't use Canon underwater but those who did - how good and up until which depth was that process?

List of Available Strobes
Unless there is one hidden somewhere on here already then I will create a list/table of strobes that are currently available. I will probably do it as an Excel spreadsheet seeing as I'm an Excel nerd and it will be easy to update. I've been out of the loop for a long time so please add to this list of manufacturers - - Inon - Supe/Fotocore - Sea&Sea - Retra - - - ...and please add to this list what you would like in the table - - flashes on full power - guide number - focusing light Y/N - TTL compatible - - -

List of Underwater Monitors
As I mentioned here I got largely over 2 hours of continuous runtime with the Weefine WED-5 Pro HD with the monitor at 30% display brightness. This is in 26° water with a new 21700 battery, at 1080p HDMI output. Official specs give 90 minutes, but I suspect this is at a higher brightness. At 3200 nits, it's very bright and 30% was fine for Okinawan sunshine in the shallows. cheers

OK Cheers! My only concern with the Weefine is battery life so I will do some more research on that.

Underwater photographers: how do you identify species after a trip?
Inaturalist does a pretty decent job and even is it doesn't get it right it points you in the right direction I have found. I recall another forum member was developing an application for marine creature ID, a while back setup to work with a lightroom catalogue. this is the post:
