Hey interceptor Gr8 article as always :-) very intersting i was thinking of you when stumbling on this video: 

I would love to know your feedback on the wb on the a1, i do think his magentas are very high ..

Sony historically had issues on custom white balance underwater until the A7S3

I have seen enough examples of the A1 not to worry about but when eventually I take it underwater you will be the first to know!

I'm sure you are not worried but i am very interested thank you !

The fellow in that video was shooting HLG3 and when I last checked that Codec was prone to error. This was when the a7s3 first came out and I was hunting for the best possible Codec to use. That sorted itself for me to using the Slog 3 Gamma 3, which requires more work in post than I suspect the HLG3 Codec needed. But I never got the color shift while shooting UW. Not with the a7s3 or the a1. I used this Codec with manual WB for nearly 200 dives. My last trip in November I did try the AWB setting on both cameras, seemed fine on footage review aboard the ship I was on. But eventually went back to Manual, while more a PITA it just felt better, probably because I knew that worked reliably.

super interesting though this raises another point what would be the difference using a ninja v

None. The gamma is set by the camera picture profile

Avoid HLG like the plague. you can see from the video the guy looks radioactive

I am deciding if underwater I will sgamut3 standard or cine but definitely not HLG

So which way did you decide to go @Interceptor121-- sgamut3 or sgamut3.cine? I'd love to hear more about your workflow after playing around with the different codecs.

for now I am solid on Sgamut3.cine
