I started doing pinhole photography when my son suggested it for for "art camp," a one week vacation we do whenever we can. The matchbox pinhole photography was inspired by alspix stuff. The mint tin camera was inspired by ck. And the oatmeal camera was made following these instructions by Stewart Lewis Woodruff.
All these photos are made on either film or paper negatives.
After making the pinhole cameras mentioned above, I started making my own - look in the "Artist's pinhole cameras" and the "Zymo 127" sets to see examples.
