Usually, the term 18% is thrown around. In reality, it depends upon how the specific meter is calibrated. As I recall, Bob Shell consulted with Kodak to write a more definitive description of what the grey card really meant. ( I can't remember if this was on the Rollei Users group or on the newsnet). The grey card reading is suppose to represent what your EV should be. In reality, it depends upon how you consistenly meter the card, the type and charactericts of the light of of the film.] Rather than make broad statements about how to use a grey card, I think you need to consistenly use it the same way and use Kodachrome to see if the results are what you want. If not, change the film speed to compensate for the way you meter. Bob Shell is an admirer of the 13 percent statement. You all need to see what works for you. Kodachrome (which I personally hate for day-to-day usage) is a great standard which you can see what is reallly happening as regards your exposure. Bill
