Just a crazy idea, I've seen a few spray cans of varnish and I wondered, if I were to apply a coat of varnish on a white surface like a wall, would this make any diffence in the brightness of the image since it becomes more reflective?
I'm guessing it would make a very glossy finish that would result in hot spotting, correct me if im wrong...
