how long does it take for the shutter to open / close?
is the time the shutter is set to inclusive or exclusive of the opening / closing?
of course it would never, NEVER have an appreciable effect on the exposure of the film, but it's fun to think about none-the-less.
like dave, i am also curious why the recipricatory factor would differ. wouldn't the samples in aaron's example both heve the same reciprocity factor, as they are both being exposed to the same amount of light?
