Underwater white balance Sony A6700

[aguriga]

Hi

I’m seeking advice because I’m kind of disappointed. I bought a Sony A6700 for trying to get better videos underwater. I’ve read that is very important to set the white balance every few meters to get correct colors. Today I’ve done the first two dives with it, and I don’t know if I’m doing something wrong or it’s the camera that can’t “white balance” underwater correctly

I’ve used this feature on land and it worked flawlessly, but underwater I can’t get the camera to set the correct Kelvin. I’ve tried to use the feature with a red filter, without it, white the white balance card illuminated and not. But it doesn’t matter what or how I use, that it always goes to 9900K and the image is red. Am I doing something wrong o it doesn’t works underwater? Please give me any clue course I’m very disappointed. The shoots I took today are worse than the ones I made with the iPhone and a case. The underwater white balance I think it doesn’t works very well neither

Thank you.

Anybody with the same issue? I’m really struggling to use that feature underwater but it doesn’t seem to work. Please I need help.

Is this problem solved?
I'm considering the A6700 as an option for an underwater video camera, do you have any suggestions?

Bottom line on photography (all). Below 30', you cannot white balance on ambient light. There is little to no "red" light for the red CCR. the camera cannot replace what is missing. At 10-15', in clear water, the camera should be able to balance in a white card, same as above water. To get proper color below 30', you MUST bring your own light. You don't want to see the MASSIVE lights and crews used by Hollywood to shoot underwater! Many wide angle scenes in films like the Abyss are shot in a DRY movie set that simulates underwater (dry for wet).

It looks like the white balance of the A6700 is closer to the A6X00 than the A7IV.
Can I manually white balance at more than 30 feet using a red filter? My other option is the A7CII but no 4K60
