My brother told me about these a few years ago but I have lost the link until now.
To simplify these cameras as much as possible I made them out of the 11×14 inch photo-paper itself. There is no film in the camera because the camera is the film. Like a salad bowl made of lettuce leaf, and consumed with the meal, the camera doesn’t exist after its utility is fulfilled. There is no machine. It is more of an arrangement than a thing.
Who needs a camera when you have photo paper? This technique produces some pretty nice effects.
