Huh, interesting. I wonder where the difference is coming from. You use a Canon, right? Maybe that plays a role? But surely that would be more an issue of raw data interpretation… Do you have any examples easily on hand?
I don’t think it’d be an issue of sea birds, would it? Blue seas would tint things blue and, if (over-)corrected, orange, I’d assume…
It is indeed a Canon, and using Canon’s DPP4 to correct the over-exposed whites using the RAW format of pictures. I really ought to research it properly, but I’m guessing that different colours (YGB) are reaching over-exposed to different degrees and getting capped. E.g. Blue is very over-exposed, Yellow is a bit over-exposed and Green is only barely over-exposed. Then when I try to bring them back to properly exposed “as one” with the histogram tool or brigtness slider, those caps and degrees are getting messed up, giving a colour balance in a manner that doesn’t reflect the original and I get a green tinge.
That, or pay more attention to whites in frame!
