You're making big assumptions that we're outside, and that we're shooting a 90minute match (football?)!
so,
Manually set your white balance to sunny conditions. Take a picture under household bulb light. 'correct' that white balance.
Now take the same picture with a correct WB setting in camera at the time of shooting....
so tell me you're getting exactly the same quality in both shots, and you didn't need to crank up the exposure slider in P'shop whilst correcting your first shot?
come off it Mike...lol.......this is a wind up just for the sake of it, isn't it?!
