My Backyard 5183
This was an experiment I tried. It's two mailing tubes, one inside the other, both painted black on the inside. The outer tube has a cap with a zoneplate in the center. The inside tube has a piece of white plastic stretched tight like a drum over the front opening. The white plastic is like ground glass and is the focal plane. Behind the white plastic is my D70 with the lens stuck into the tube to take the shot of the "ground glass".
I got this idea from Adam Holte.
