Here is something this long time 35mm user doesn't understand. I'm only using a MF but this would apply to any one that uses an incident meter. I figured you guys would be able to explain this as you no dubt have more experiance. Lets say you are shooting a hall with a large painting at the end. There are other paintings on the sides of the walls so you want to show that they are there, but you really would like to highlight the big painting at the end of the hall. Whether it is lit by strobes (usually a no no in a art gallery) or the natural light coming from windows, you have your camera 40 feet from the big painting. Now the question is, if the camera is that far away, how do you figure in extra exposure? Certainly there is some light fall off over that large distance. With a reflective meter, you are reading the light that comes down the hall. However with the incident you are measuring the light falling on the painting. Do I make myself clear? Thanks. Ric.
