"Unfortunatley" (or fortunately depending on your point of view) film is non-linear in its response and you can't just "up" values willy-nilly. You'd have to know which film, its charateristic curve, the placement of the scene luminance values along that curve, flare, etc., etc. It would really be nice if one could do that as the days of under or overexposure would be gone. Maybe digital shooting RAW? Seems this is a panacea for all ills in the modern world. OK - time for another cup o'java or maybe a nap. g'day! andy
