This is an experimental Pinhole Camera.
Almost all of the others of myne started as such, more or less used by me to experiment with light and time but on this one I want to see how light works in relation to slit openings. This camera permits a rather easy modification of the slits and in time I hope to understand better how long exposure photography works with slit cameras.
