Okay, so my shot is WAY too warm, like almost all reds and yellows. So, I tried to do things with the color balance, but nothing seems to work. I can only get tinges of other colors, and not anything that's really pure white. So, how would someone attempt to adjust a white balance on a JPEG? I'm really patient, so it doesn't matter if it takes a few steps, or takes a lot of trial and error. I was trying the color balance one number at a time!
