A contact print is a photographic image produced from a film, usually a negative, occasionally from a film positive. The defining characteristic of a contact print is that the photographic result is made by exposing through the film original onto a light sensitive material pressed tightly to the film. In the dark, or under a safelight, the printer places an exposed and developed piece of photographic film, emulsion side down, against a piece of photographic paper, briefly shines light through the negative, then develops the secondary paper into a contact print. The image in the emulsion has been pressed as close as possible to the photosensitive paper. An exposure box device called a contact printer or a printing frame is sometimes used within a light controlled space called a darkroom.
