Bruce R. just gave the correct answer, "The most accurate metering is done with an incident meter that measures the amount of light striking the subject." As long as the photo cell's colour sensitivity is close to the colour of the light being measured, all is well. Reflected light meters, especially spot meters, are prone to huge innacuracies. If the cell does not have linear colour response, or worse, non linear colour response at different EV values, metering accuracy is compromised. Lack of knowledge by the photographer is what causes most exposure problems with spot metering. William Robb
