Hey all,
I have a major question to ask. I recently shot a theatrical production and in post have been having a blast at playing with the photos. However, when I got to the head shots, I can not, for the life of me, figure out how to correct for low light. I have done many different techniques, and it seems that I can not figure out how to balance African American skin tones. almost all of my photos come out either really yellow skin or green hair. I am really in need of some assistance. THANKS EVERYONE!

Can you post a sample photo for us to tinker with?

Ill try! I have had problems attaching photos....but Ill try.
It looks fine in the editing program but seems to cast its yellowness in printing..I have checked my printer and everything is calibrated with that.

I'd have to say its your monitor if that looks okay to you. It looks hugely yellow to me on 2 different monitors.

Edit to say - try b/w :)

The original looks very yellow on my monitor, to be honest, but the other colors in the photo look to be right where they should be. So I desaturated the yellow channel by -40. Then I applied two different curves. The first is a 3 point curve, pulling the upper point down slightly to tone down the highlights, and the lower point up to lighten the shadows. This leaves the photo a bit flat, so the second curve is also a 3 point curve, but this time the lower and center points are pulled slightly down and the upper point is left where it is.

I hope this at least gives you some ideas. :D

I had a play around with it as well, and came up with similar results to karmabreeze. The problem is the yellow cast. Try converting to B&W perhaps.

Did you do a white-balance before shooting?

I think the underlying problem here is lighting.

One good way to check for color cast is to use your eye dropper tool and check out the info palette in PS. If you point to something neutral or white, you can check and see if any of the values greatly differ from the rest - as the yellow does in this case. Color balancing for the opposite color (blue for yellow) will help a little.

Did you shoot these in jpg? If you're not going to set a proper white balance before you shoot, you might want to consider shooting RAW so that you can set it afterwards.

Ill try that.. I doubt it is my monitor as this is not one of the pics that look yellow...however it was one that I could not get right. Thanks karmabreeze. And jhonan-bl/wht is not an option for this project, but thanks for the ideas. Yes, I do white balancing before I shoot. This was a theatrical performance on opening night so the lighting was the best I could get.

Desaturating yellows makes quite a difference. I thought -30 to -35 was enough though. And try darkening the highlights a bit using shadows/highlights adjustment. Otherwise I like the idea of black and white.

Edit: ignore the b/w part then. I didn't see your comment before posting.
