I love the simplicity of the whole concept of pinhole imagery. I've made several cameras and even used an old 8x10 field camera as a pinhole camera with very good results. (I've also had some very poor results. There is a learning/practice curve.) I've taped simple cameras to pillars inside a large photo studio and made week-long exposures. Pinhole photography makes the concept of time very elastic.
The 8x10 images were made on film, and when contact printed, were amazingly sharp, especially at focal lengths of from 5 to 10 inches. The inherently low contrast allows a fairly astonishing compression of scene brightness ranges as well, especially with a pyro developer.
