This has had me thinking for a long time...people say use white balance...but let's say you are shooting at sunset and the white card is now a golden orange (glow from the sun) you wouldn't want to white balance would you?
I think that alot of the time a white wall will not be white when there is a warm colored light shining on it...
Now if the wall is now red because we're shooting in a red lit room...you would want it to show red on the white wall rather than white
