I work at a University of California art department. One of the photo assignment is making a pinhole camera that allows one shot. The students really are careful not to waste that sheet of film or paper. They're shooting mindfully. They have to take the film and process it with great care. If they blow the shot, they have to reload the camera and do it again. The drudgery itself is a revelation of the analog world. You can't chimp a pinhole camera.
