I am interested in making my own zone plates, zone sieves, and photon sieves at varying focal lengths and ring counts. I am using the zone plate generator found on Mr. Pinhole.
I am having trouble finding a 35mm film that has a clear PET film base that I can use to photograph the zone plate target And develop to get a dmax of log 3.0 while keeping dmin equal to film base.
Anyone out there try this before with success and have some good film recommendations?
