I know this is kind of a strange question, but I hope someone can help anyway!
I'm trying to figure out how to properly meter a film exposure with no lens on the camera - in other words, controlling it just with exposure time/shutter speed. I assume that if I were to calculate an exposure time for a hypothetical f/1.0 lens (hypothetical because I know they exist, but I definitely do not have one!), it would still be too long of an exposure, correct? How many stops does an f/1.0 lens absorb (in other words, how many stops should I decrease my exposure time to convert from an f/1.0 exposure to a "no lens at all" exposure)?
