This may be a dumb question but is there any #software or site that will look at two images that are identical (or nearly so) and tell you what settings you'd need to use in #ffmpeg to make one look like the other. The idea would be you could take screen grabs from two #videos taken with slightly different lighting (or processing or whatever) and try to make them match up. I'm sure there is probably professional software costing big bucks that will do this (or maybe people who can work out that sort of thing in their head) but this is just for a once in a blue moon type of thing, and it doesn't have to be perfect.
