Dave, I agree on the paper vs real film cost dif! I'm thinking of using some Arista lith film I have. It worked well in the oatmeal cans.
Jim, thank you for all that info! And I was thinking about 6" or 7" to start. I have a handy little magnifier that has a measuring device built in (left over from bloodspatter analysis ) - it works great for helping make pinholes.
If I can get something started soon enough, I can do a test or two before the 28th. Knowing me, I'll be winging it, though. :rolleyes:
No idea what my eventual subject might be.
