I've two pinhole cameras, one canned and one wooden. The one I used for this picture is the wooden one and I made it with a pencil jar. For these boxes/cameras I use photographic paper directly. I take the photo and go to the dark room and I develop it; I put a new paper and take another and I come back and I develop it; And so I spend a few hours doing this. It's really nice :))
