A luminogram is an image, usually made with an artistic purpose, created by exposure of photosensitive materials to light without the intervention of an object. ==Technique== The luminogram is a variation on the photogram, made in the darkroom directly on photosensitive paper and chemically developed and fixed normally. While the photogram employs the shadows of objects, in the luminogram the light is modulated by varying the intensity through distance from the photosensitive surface, by the power or shape of the light source, or tempered by filters or gels, or by moving the light, often a low-powered torch (flashlight). The paper can itself be shaped to create the desired effects in the final image. The photography theorist and practitioner of the luminogram Gottfried Jäger describes this as "the result of pure light design; the rudimentary expression of an interaction of light and photosensitive material… a kind of self representation of light." ==History== ==References==
