The F5's manual says that the colored filters used for black and white can cause the RGB meter to give incorrect results. It recommends using center-weighted or spot metering with colored filters and black and white film. Using a colored filter with color film isn't any different than photographing a scene of a different color. You probably want to fool the meter in that case. > I say this as an F5 user who has yet to see > a difference based on color metering.

All of this discussion about whether a meter can provide correct exposure assumes that for a given scene, there EXISTS one correct exposure. It just ain't so. All meters try to get as much of the scene's brightness range inside of the films range as possible. A 'smart' meter (like the F5's) can even try to guess whether it should chop of the bottom or top of the scene's brightness range when everything won't fit (which is often). That's nice when it guesses right -- but it's still only guessing. Only the photographer knows what part of the image he REALLY cares about, and where it should go in the film's density range. You and I could both be standing on the same beach at sunset photographing the same person -- you want to expose for the background and have the person recorded as a silhouette, I want to expose for the person's face, and let the background burn out. What kind of meter's going to know that? Use the spot when exposure matters (and you have time). If you don't have time, and you think that RGB might guess wrong, bracket. The more things change, the more they stay the same, huh? You don't really want your camera to be smarter than you anyway, do you? -Don
