After seeing the DOF adapter, and also your pinhole camera, I remembered the Boss Screens.

They are quite expensive for this application: http://www.stabitech.nl/Bosscreen.htm

but it is basically a layer of wax in between two pieces of glass. They have the advantage of being grain free, and fairly bright. I believe they are also quite isotropic, so one shouldn't need the fresnels.

Interesting. The plastic paper is the cheap and easy go-to for me, but not what was used on the pinhole obscura.

I believe I have one in one of my 4x5 cameras, but I need to find it. It has lines, but for a proof of concept, it shall work.

Prof, maybe you can find some students that want to play and try to replicate the boss screens?

Not really computer engineering computation photography work per se...
