A spherical shaped film plane would be ideal to maximize the edge
"sharpness", I guess I should say: to minimize edge softness (instead), as
well as minimizing the fall-off. Practically, though, cylindrical is the
shape most suitable to accomodate either film or paper. I believe that in
one of the 2 editions of Renner Pinholo Photography books there is a picture
of a guy that made a spherical film plate dug in the ground and B&W paper
placed to conform the shape of the hole.
