DIY Paper Pinhole and Solargraphy Kit. Assemble in 1-2 hours. No knife or scissors needed. Use 35mm film (not included) preferably ISO200. Pinhole cameras do not have optical lenses. Film is exposed by light through a tiny hole in front of camera. Because there is no lens, the image will be in focus at all distances. Best pinhole pictures are taken on a bright day. The camera must be very still when shooting. Exposure times range from 5 seconds to hours and sometimes days.
Technical Specs: Film type: Aperture 1.16mm. Focal length 20mm. F stop F/130.
