I'm wondering if it worked better because you were shooting through more water and closer to shooting through the same amount of water as you were filming the guests. slates and fins unless someone else is holding them are at a relatively close fixed distance.

Is this tested in air or in water? As I understand it the diopter power increases in air compared to water, so the focus point comes in closer. That combined with increased spacing may be enough that it focuses inside the lens. If you have not tried it in water perhaps do that first? If it is still an issue are there any alternative ports you could try? For example the 5502 port for 60mm macro in combination with a 1"extension. Looking online it seems FL ports are discontinued so you would be looking for second hand ports.

Does anyone have any insight or knowledge on the maximum gap from the lens face to the port glass for a nauticam wet lens ( SMC-1, MFO-1, MFO-3 ) to focus through? I have a canon 5d IV that I use in an ikelite housing and located a flip adapter to allow 67mm threaded wet lenses to be used. I tried it out with a nauticam SMC-1, with bad results. I'm using a Canon ef 100mm f2.8L lens, the lens sits approx 1" behind the port glass when assembled(no way to change this) The adapter places the SMC-1 essentially right on the port glass, Making the effective distance from the lens face to the SMC about 1" I took it out on a couple dives and I couldn't get it to focus at all, is this possibly a user issue or hardware combo issue? Im concerned the issues may be caused by the interior "gap" from the lens to the port glass Any help is appreciated!

Hi, Welcome on board! Ciao

Hi Erik, Welcome aboard! We hope you will enjoy the community. Ciao

Aloha! My names Eric, based out of Kailua Kona, HI. I've been pretending to be an underwater photographer for a few years now and playing with expensive toys. I shoot a Canon 5DIV in an Ikelite FL series housing(trying to keep that platform and combination going as long as I can!), mainly macro/fish portrait type photos. I'm always looking to learn new tips and tricks and further my bubble blowing activities

Hello from Singapore. I love scuba and I love videography. Thanks for setting up and maintaining this community - have learnt alot from the forums and hope to contribute a small bit back someday.

Month ago I planned to build my own reflectors for my Retras But I had not enough time to continue my project for the moment. I allready bought some painting bomb to obtain some reflecting surface. Like the original Retra reflector but not as heavy as the original and second point with the possibility to change the size of the output

I didn't notice any uncontrolled stray light..

I was an underwater cameraman on Sipadan for many years, chasing guests around and filming them, so I had to adjust my white balance constantly as we changed depth. The easiest and most reliable method I found was simply pointing the camera at the sand and setting my white balance from there. The sand usually had enough white and natural colour variation to give me a really good balance for whatever depth I was shooting at. Some people recommend using white fins as a reference. I tried that as well, but I found that balancing off pure white tended to leave the image looking a little washed out compared with using the sand. Using pure white as a reference on land is very different from using it underwater. Underwater, there’s a lot more happening between the lens and the subject—the water column is constantly absorbing and filtering different wavelengths of light, and that changes significantly with depth, visibility, and ambient light. For me, the sand gave the camera a more natural reference point for the actual conditions I was shooting in. It wasn’t technically pure white, but that was actually the advantage. It consistently produced more natural-looking colours and a better overall image than balancing off a bright white object. I also experimented with carrying a white board and a dedicated white-balance slate. They worked, but when you're constantly moving and trying to keep up with divers, they just became another piece of equipment getting in the way. If you have the time and aren't worried about moving efficiently, they're definitely worth trying. For me, though, the sand was quick, easy, always available, and gave me the best results. Hope that helps!

I believe that such a reflector causes a lot of uncontrolled stray light, thus preventing the function of the reduction ring of controlled and reduced light emission angle. But I am happy to be proven wrong. 😁

I was fortunate enough to live on Kapalai for 5 years. You are not wrong about the Jacks. Barracuda Point when it went off was Disney land for diving. Nice Photo, you were right in there :)

Good luck

PC on Ethernet but I also try Wi-Fi... I hate using Wi-Fi, it's only for our phone or tablet when mobile in the house, on the desk connected over cable. ;)

So I'm lost 😁 Was your first pc/browser?

No no thats not the problem.. The 3rd PC use the same connection I search a little and found with Copilot That there is a known problem with some forum and Invision is one of them. I tried to make some changes in the setup of edge (waht Copilot recommend me to do) but nothing works It seems that the problem are in combination of Edge and Win11... I continue to try ... It can be good for you if I found something... I'm sure i'm not the unique with this kind of problems

Do you have some filters on your router? Try using a phone on the mobile network, not Wi-Fi.

From the PCs with the latest patches from Microsoft no "Drag files...." and no Paste. The old Surface is still making updates... 😁

Hey there Apologies for the late reply. Yes I always use Peaking, it's a huge help, in darker waters I use find edges. Having a bright monitor is a must as well.

I didn't start this PC since 2 or 3 month... now it want to make updates... Let's go... I'll see what hapen Now go back to the main PC to show if...

It works on this topic.... Paste ok and I have

Yes here I see... but moment it is on the third pc I wanted to test and the paste also work

Do you see the select files to upload here or just able to paste in the screen shot?
