Cookie Tin Pinhole
Another simple pinhole design for sheet film--I wanted a different one without the curved film of the paint-can pinhole.
About f/230, and the diagonal coverage is about 80 degrees (like a 28mm lens for 35mm cameras). The lines drawn on the tin are the "viewfinder": if you eyeball along them, you can estimate the edges of the field of view.
The shutter is one of those soft vinyl magnets with a little nub of hot-melt glue on it.
