I'm a raw shooter and shoot almost everything in the camera's daylight
or flash white balance so the JPEG previews look about like what I
expect to see. I post process everything but white balance adjustments
are relatively rare except for occasionally removing a bit of blue from
heavily shadowed areas. Yes, I do have a WhiBal card but almost never
use it.
I understand how shooting an image of the WhiBal card tells me how to
use that image to properly correct in post but I do not understand how
adjusting the white balance in camera can have any effect at all on your
raw files. Am I missing something really basic? Maybe something your
MF camera does that my lesser digicams don't?
