Yes it does have this feature. But my understanding was, that white balance on camera is not that important when shooting in raw, as you can always change it easily in post. But strange is that you say I have two different casts of colour in two different parts of image, how to correct for this?Did I miss it or did everyone miss the obvious? The color balance is set to auto, and it's not correct either. At least on my monitor.
I looked at a couple edits of the original and you can see the hand looks green while the face looks a merkish yellow. How strange.
OOps C&C poster should add some form of advice. Well.... When I shoot with flash or external flash(s) I don't ever use auto color balance. I set color balance using kelvins. Does your camera have color in Kelvins?
