Thanks @Nando Diver . Do you use dive lights wuth such presets?

Yes..

2x 5000 lumens each (getting too much red)

2x 2500 lumens is enough

So we come back at the topic :-)

I appreciated the suggestions provided by@Davide DB so far.

I also use a couple of diving lights getting to much red due to both torch diving temperature and gopro wrong white balancing.

I'll try to do my best

you can use gplog preset and later apply Lut for gopro 13 in davinci resolve.

I have GP12 at the moment

Looking forward to test with AOI UWL-03 Wide Lens, they had a big scratch and ive send to Holland to replace the lens.

Have you received back the AOI lens? Did you test such lens with the above said labs commands?

Bye

haven't receive the lens yet.

Be aware that kelvin value from the light underwater is a starting point to set your camera but not the right value in most case as the light coming straight from the video light will be filtered by the water on its way to the subject and then the reflected portion will be filtered again by the water on its way to camera sensor.

So if you are diving in blue water with a daylight kelvin value for your light, shining a subject 1m away, your light actually travels 2m of blue water and will hit your sensor with a bluer tone. You might want to decrease your kelvin value if you can set it on your camera to compensate for the bluish pattern of light.

@eocean-eu

I have a couple of diving lights at 5.5 - 6K kelvin. I reduced to 5K kelvin the temperature setting of my GP12 to compensate a reddish tint of the video footage, following the indications of @Davide DB .

Exactly the opposite of the bluish you say.

May be I didnt understand your post.

You did what needed to be done. I was probably not clear enough

If you increase your color temperature in the white balance settings, the resulting image will go warmer. On the opposite, it will go colder at lower K... This is a bit confusing because this is the opposite of how Kelvin works for light source with lower values meaning warmer color and higher colder ones. But it's all about compensation for the camera which is why this is inverted.

I am attaching a picture made with my trusty GH5s in a pool playing with the Kelvin settings for white balance. The external light is the sodium light from the pool and is constant accross my experiment. If you have a "daylight" Kelvin value for your divelight in blue water, your actual kelvin value from the light is actually higher which might results in the camera more in reddish tone. To compensate for this, as you did, lowering the K is the way to go.

@Gmsalterego you got from @eocean-eu the same reply as mine, plus a nice explicative image.

Thank you all, nice to have such explanations
