At least in Canon DSLR RAW files, all adjustments are simply parameters recorded within the file - the actual data of the image does not change whatsoever. The WB, like all other adjustments are applied in software in the computer after. Camera parameters like WB become the default for RAW files, and are applied in camera to JPG images before they are written to the CF card. But I don't worry too much about any of that bullshyte, because I NEVER SHOOT JPG. I do all my adjustments by hand in Capture One LE. I have found by keeping the camera at daylight WB that I at least get a consistant default WB. That makes changing any series shot in the same light easy to WB with one click, and anything shot in sunlight needs no WB change. I do small WB tweaking when I feel it improves the image of course. All other parameters I tweak entensively in C1LE. And this takes only seconds and is the part I enjoy - the digital darkroom. So fiddling with things like WB in camera, or shooting in AWB just makes more work for me. Of course for someone who does not own a copy of Capture One, things are going to be much different. The Canon RAW conversion software is enough to make anyone shoot in JPG and worry about WB.
