This question came up and I wasn't sure if it was on topic or not:
Currently the title and body of the question do ask about both video and pictures with the banding issue, but originally it didn't mention photos at all(see edit history). It was my suggestion that prompted the edit to cover photography.
I do not know if banding in video is caused by the same issues in photography, I would assume they are very similar if not identical issues. But the question is, if it is an issue in both photography and videography, should the question really be written to address the photography piece?
