curved plane camera

[darinwc]

How much light falloff will there be in a pinhole camera with a curved film plane?

Thanks for any help.

Instead of cos^4, it should be cos^2, maybe. Not sure. Different amounts in different directions, because it is only curved in one direction. If you had spherical film, then maybe only cosine.

In otherwords, it helps in the curved direction, but not the other. Try it.
