Pinhole Photography
Dark room / box photography is photography without a lens. A hole with a diameter of 0,25-1 mm takes replaces the usual lens of a camera. Light passes through this hole, and produces an image on the film or emulsion inside the box providing a dark medium.
The camera used in this technique may be small or big. It is possible to make use of a seashell, of a coke-or candy-or even a matchbox or a big object such as a refrigerator, a caravan, or a room that does not let in any light. As a simple principle, any closed medium that does not let in light can be turned into a Camera Obscura by means of the light passing through a pinhole.
All kinds of Camera Obscura force the boundaries between. the real world and the world of imagination because they yield images beyond the scope of normal photography.
