So just before sunset today I was playing with my chocolate box pinhole camera using 5x7 paper and litho film, and a thought occurred to me. Would it be possible to use clear epoxy to create a droplet lens on top of a pinhole. The surface tension should create a nice smooth and round surface as long as you can center it on the hole, I think it should work. I just put a few drops on a very thin piece of adheasive foil tape (my current pinhole medium) and they are drying. They do form a nice round shape, and by accident one has even formed a tiny bubble under the epoxy right above the pinhole. I tried doing some google researching, but have not come across any info on such a process. Anyone ever do something like this before? or read about it? Would the droplet lens be able to form a picture? How would such an image come out?
