Speaking of wedding photography, I was asked by a close friend to be her wedding photographer. All things said and done, I am now post processing a lot of photos. I'm working on getting consistent colors on a per venue basis. The result is a bit cool for such a joyous occasion, so I'd like to shift the white balance to give the photos a warmer touch. So now my question is: how can I shift the white balance automatically even if the photos themselves are set to different color temperatures? I'm using Aperture and I also have a copy of Pixelmator.
