Wolf Howard is a member of the Stuckism Photography group and takes pinhole photographs. He uses a light-proof wooden box 4" square with a fixed-size pinhole in the front. Photographic paper is placed at the back of the box. There is no lens and no viewfinder, so he estimates the aim of the camera. A wooden slider allows light into the box for an exposure which is between 40 seconds and 5 minutes. The camera is placed inside a light-proof bag to replace the photographic paper.
