No worries. Now you can see it, buy big! 😜

End up to 280 GB of material in 3 days. Wow, good luck processing all that! You'll need a holiday afterwards.

I have seen them thanks - they are fantastic it looks like strobe was used as there is too much light on the sharks face to really be from above strobes it is!

I guess you know NIck More's fantastic slow shutter images of blue sharks : https://www.divephotoguide.com/underwater-photography-special-features/article/motion-blur-blue-sharks-uk/ Personally I would definitely bring a strobe, -maybe just one would be enough, just to get at least a sharp front part of the shark-, sometimes available light images look a bit washed out when you need to balance the sunlit surface and the shark itself .

Back from a land-based mission. Cards from Angelbird (v60 rocks!) 2 Lacie rugged for backups and Angelbird cables (i haven;t seen such a speed to transfer images from HDD to HDD). And 1 Samsung T7 SSD for first data unload Use Canon R7 (both JPEG and RAW) for underwater + DJI drone for photogrammetry data collection. End up to 280 GB of material in 3 days.

Yes. https://www.metabones.com/products/details/mb-ef-e-bt5 I think the Mark IV works also but im not 100%. The Sony native Laowa 8-15 is also coming "in near future", if you have some time to wait (and believe it will be good).

So you had the same distance to the mat? The @28 behind wwl should give a bit more FoV than 16 recti behind a dome. Looks almost the other way around.

Is this Metabones the correct one to use for a Canon 8-15 on my Sony? Metabones Canon EF Lens to Sony E Mount T Smart Adapter Mark 5 EF-E-BT5 I can buy one secondhand. Thx you amazing people

Hi Slim! A warm welcome to Waterpixels. Great to have you with us. Enjoy the forum! Best wishes

Still available.

Dear All I am happy to introduce myself to everyone in the Forum. Based in Zurich I dive for just a little under 3 years and was hocked in a way that I still do not understand why I did not get certified before. I started UW Photography pretty early with at "Frankenstein" second hand SeaFrog Housing for my A7RIII combined with Sea&Sea lashes used Rigging and floats. The thing was a mess but I learned a lot. I am looking forward to read up on your ideas and to contribute. Again Hi to everyone Slim

my thoughts are: if no strobes i can use program or similar to get fast shutter speed with available light- also much easier bobbing about near the surface without a big rig downside is that it might be a dark day - slower shutter speeds - and underneath of sharks could be very dark i can’t work out from the images if flash has. been used

thanks for that I see it now

i’m going on a blue shark day trip snorkelling only with blue sharks in july curious what you all advise about using strobes. it would be much simpler using natural light but would some fill in make the pictures much better? the attached images from the tour company website

great- thanks for all the advice

It's not a subforum but a different part of the website, specialized for sell/buy items with a bunch of specific features.

One 128 card per week plus one spare.

It does seem that the flash just overpowers what you might see in existing light. Try no flash, long exposure or higher ISO. Where does this anemone live?

I cannot say about WWL, since I never used it. I Have WACP-C/Sony 28-60mm and can say that flare occurs very seldom. Here is one of the few examples I have, when I got flare in the photo, when I photographed against the sun:

And this is how it looks like when I increase the saturation (not selectively, this would be a lie) in Lightroom.

Dear Hiloboy, dear all! I was contacted by pm but would like to post my (extended) answer also here because I think it might be of interest for others es well, especially since my above answer might be unsatisfactory for some of you. To be honest: In fact, it somehow is. Honestly, I don't think your photo looks bad. Mine looks very similar. I think our eyes are very easily fooled in this situation. They somehow "sense" that something unusual is going on, that there is light present in a color that shouldn't really exist under those conditions, or at least these colour does not exist anywhere near or around the red "glowing" object. There are probably other effects involved as well. Our visual system tends to perceive this red color as a very strong color accent. Depending on the camera settings, the automatic white balance may also be working against the effect to some extent. Sorry, but for the moment I don't have a better explanation either. In fact, fluorescence underwater, or "fluo diving", is also very interesting from an ecological perspective. Why do fluorescent organisms occur mainly in shallow water? Because GFP acts as a natural sunscreen. The high-energy green and blue light is converted into lower-energy orange or red light. This reduces the risk that high-energy radiation will cause "sunburn" and thus damage or destroy tissue. And now something a bit more off-topic regarding red light underwater: For us photographers, it is often helpful to use red light as a focus light because it disturbs many underwater organisms less, especially fish. Why is that? Because beyond a certain depth, red light no longer exists underwater. As a result, there has been little or no evolutionary selective pressure for the development of sensors (eyes) that can detect red light. After all, why would an organism "accidentally" evolve a sensor for a signal that simply does not exist in its natural environment? Most fish are unable to perceive red light, although there are notable exceptions. More on this in just a moment. Still not enough crazy facts about red light underwater? Some fish actually fluoresce red! They use this fluorescence to communicate with members of their own species, and their "language" cannot be eavesdropped on because other fish species cannot see it. It's like transmitting on a radio channel that no one else can monitor. As always, exceptions prove the rule, because, of course, these particular fish species are able to perceive red light themselves!

Can you post a link to the new forum ?I do not see it as a line item in the forums . I can access it thru a goggle search but thats not right.

Never used a WACP and understanding that people can have strong opinions and varied experiences, but I cannot recall ever having a flare issue with the WWL-1. I do not think it prone to flare. Less so than my dome. But my dome is acrylic, not one of those high dollars Zen glass domes ;). And I like to shoot back into the sun. Photos with WWL-1 and either a Nauticam NA-R50 or NA-6400.
