Welcome to /c/birding, a community for people who like birds, birdwatching and birding in general! Feel free to post your birding photos or just photos of birds you found in general, but please follow the rules as outlined below.

  1. This should go without saying, but please be nice to one another. No petty insults, no bigotry, no harassment, hate speech,nothing of that sort! Depending on the severity, you'll either only get your comment removed and a warning or your comment will be removed and you will be banned from /c/birding.

  2. This is a community for posting content of birds, nothing else. Please keep the posts related to birding or birds in general.

  3. When posting photos or videos that you did not take, please always credit the original photographer! Link to the original post on social media as well, if there is one.

  4. Absolutely no AI-generated content is allowed! I know it has become quite difficult to tell whether or not something is AI-generated or not, but please make sure that whatever you post is not AI-generated. If it is, your post will be removed. If you continously post AI-generated content, you'll be banned from /c/birding (but it's obviously okay if you post AI-generated stuff once or twice without knowing you did so).

  5. Please provide rough information location, if possible. This is a more loosely-enforced rule, especially because it is sometimes not possible to provide a location. But if you post a photo you took yourself, please provide a rough location and date of the sighting.

It's actually really there in the sense that the grass the goose is standing on is very green and reflected off their chin! :)

I wondered the same for a second when I went through the pictures at home.

Thanks. What's worse, is that I lost quite a few attempts to this problem today: white gulls and the like, against dark backgrounds. Trying to remove over-exposure just leaves a vivid green discolouration,

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..

Oh, right: I'm using a nikon z6ii with a sigma 150-500 mm lens.

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!
