Having difficulty in low light with color balance results. Using 20D with 550 EX Flash.
Any thoughts are appreciated --

Shoot in RAW if you are shooting in difficult lighting, you can pick a custom white point, or choose your WB setting in post processing withough loss.

FWIW - I've noticed my WB is hit or miss whenever I use a flash on my XT. I've tried both the 420EX and now 220EX and the white balance can be all over the place. Unlike when I'm not using a flash and the WB seems to be spot on all the time (or at least consistent among groups of photos with similar lighting.

With the speedlight just set the white balance to the flash mode and then use the WB grid to make changes. Usually I will have to go 3,-2 in small rooms with white cielings to get skin tones back to normal. Experiment and you will see what works with you.



note: by 3,-2, I mean over 3 towards the right, then down 2 towards the bottom.

Thanks for the tip Juan. I should have mentioned that I experience the problem primarily outdoors when I'm using the flash as fill. I shot a bunch of headshots with an actor friend the other day and the WB was literally all over the spectrum. Some shots were too yellow, many too red, a few were magenta city. It was very strange. I was using auto WB and it was around 5:30PM. I was using the sun to backlight her. When I turned the flash off, the WB was fine.

I'm shooting another actor today and I'll try using the flash WB preset though I'm a little concerned that will leave the image a little cold at that hour of the day. As far as manually WB before each shot that is highly impracticable for me. It's enough to focus, zoom and compose/frame my shot. And with these headshots, I feel the need to rattle them off pretty quick to capture the moment. Otherwise the actor's attention may stray.
