Tony, Re the rules of exposure you posted:

Average caucasion skin is one stop lighter than the grey card - a Zone VI. You can take a meter reading off your hand and then close down a stop that will get you in the ballpark for exposure. A medium red is probably the closest to a grey card. >In practice, I've found that they can >differ and it sometimes, but not always, shows in my slides. How do you >all check your exposures? (Carry a gray-scale card around?) When shooting transparencies I almost *always* use a hand held incident meter. It is usually right on, no need to bracket. Saves worry and money on film.
