A pinhole camera is a photographic device without any lens. Usually, pinhole cameras are made by hand, although there are also factory-made copies. The simplest pinhole is an opaque box with a hole on one side and a piece of film or photographic paper on the other (by the way, the smaller the hole, the sharper the image will be). Pinhole cameras were once made of Pepsi-Cola cans, cassettes for 35mm film, shoe boxes, barrels, refrigerators and even vans.
Pinholes are often made with a movable back wall. This allows changing the distance between the hole and the light-sensitive material. For instance, pushing the wall back can produce a ‘telephoto lens’ effect.
