Not to be argumentative, but you have to view the film at some
magnification, don't you? How can you establish DOF on the film without this
as a parameter? Or are you  referring to the point at which the lens
resolution exceeds the film resolution, so that variations in resolution of
the projected image on the film aren't captured??
