I got into color grading still photos last summer. In my case it is not "correction" to the truth but rather making a set of images conform to a brand image. (I had a day when I went out to a beauty spot and packed the wrong lens, I made up a story about another photographer who had a camera from an alternate timeline and developed a method to take distinctive pictures with a cheap lens)

Funny the only kind of picture that I don't color grade are sports photos because I don't want to mess up the color of the jerseys, though if I was careful in how I did it, it would be OK.

I have been struggling to develop a reliable process for making red-cyan anaglyphs and one step of the process would be a color grade that moves colors away from reds and cyans that would all be in one eye or the other eye. I've got to figure out how to make my own LUT cubes to do it.
