Unfortunately I missed the initial posting, but the sharpness or
otherwise of the "shadow" caused by a hair (or whatever) just infront
of the film plane depends on the size of the exit pupil (and aperture
setting) of the lens. Therefore it may not be noticeable at wide
aperture but sharply defined at a small aperture.
Been there, done that ;-)
I once ruined a whole roll of irreplaceable shots (aren't they
always?) on a Bronica because I hadn't noticed a hair loop stuck to
the film magazine before I attached it to the camera.
