My children's school, for whatever reason, has red/orange lights at the rear of their auditorium stage. When the kids are at the front of the stage, no problem, they look normal. But if they're anywhere to the back, they look reddish.

I assume there's nothing I can do about that (i.e. restoring their color), except maybe get close enough that my flash will illuminate them more than that light.

Any other ideas? Is there anything that can be done in post-processing?

thanks

Manual whitebalance. Point at a white piece of paper under that lights. Or adjusting the whitebalance manually and set it more towards blue.

Thanks. I forgot about shifting the wb!
