darkroom equipmentPhotographic EnlargerAn enlarger is a specialized transparency projector used to produce photographic prints from film or glass negatives. Prints made with an enlarger are known as enlargements. Typical enlargers are used in a darkroom, an enclosed space from which extraneous light may be excluded; some commercial enlargers have an integral dark box so that they can be used in a light room. Principles of operationA condenser enlarger consists of a light source with mirrored reflector and a condensing lens. Alternatively, a cold light enlarger has a fluorescent light tube masked by translucent glass as its light source. Browse a huge selection of and and find exactly what you want nowSearch. The directional light then passes through a film holder, which may hold sheet or roll stock photographic negatives and transparencies, which have been previously exposed in a camera and developed. Color enlargers often have an adjustable filter mechanism between the light source and the negative for color correction with controls for the amount of cyan, magenta and yellow light reaching the negative. The negative image is then projected through an adjustable iris aperture and focusing lens to a flat surface upon which is mounted the sensitised paper to be exposed. By adusting the ratio of distance from film to lens to the distance from lens to paper, various degrees of enlargement may be obtained, with the physical enlargement ratio limited only by the structure of the enlarger and the size of the paper.
