This is a toughie. I shot a series of headshots in the conference room of an office. There were big spotlight-style lights overhead, probably florescent? I asked if some could be turned off. Found that I had to have all on or none on. No in between. I would have preferred none on but then the lens could not auto focus as it was dark. So I kept them all on. I shot in RAW. But the problem is that the skin tones on some are yellowy-greenish. They looked jaundice. In order to fix that, the rest of the image becomes way way too blue/red. I used gray background paper and have been using that as a rough color guide (it's not the 18 percent gray Savage paper but a medium gray). I am wondering if I can adjust various sections of a photo differently re color? In ACR. I don't think so but wanted to see if anyone has any suggestions. Thank you!
