Speaking of the difference of shooting outdoors as opposed to shooting in
the studio, why are the outdoors negatives so much more dense. If I am
taking a meter reading both inside and outside shouldn't the negatives
ultimately be the same density if I am rating the film at the same ASA. I
know that Carl has mentioned the difference between using a spot meter
reading outdoors as opposed to a flash meter reading in the studio. But
shouldn't it all be relative?My shoots from outside are much more dense and
stained than my studio shots.
