If you spot meter on an 100% white area, the camera will adjust its exposure to render it 18%grey. How many stops of compensation will I need to apply to make that white area ALMOST perfectly white (but not blown out)?
I would guess that it will depend on the dynamic range of the camera. If the dynamic range of the camera is supposedly 10 stops, does that mean that a +5 stop compensation will do it? That is a lot more than the "common wisdom" number of 2 - 3 stops.
I would appreciate some input on this subject, thanks.
