My Photogram's I Made
M My Photogram's I Made A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear grey. [ 1 ] The technique is sometimes called cameraless photography . It was used by Man Ray in his exploration of rayographs . Other artists who have experimented with the technique include László Moholy-Nagy , Christian Schad (who called them "Schadographs"), Imogen Cunningham and Pablo Picasso . [ 2 ] Variations of the technique have also been used for scientific purposes.
