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 or negative film and then exposing it to light in darkroom. 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 will appear to be white; those exposed through transparent or semi-transparent objects will appear to be grey.

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 Christian Schad (who called them “Schadographs”), Imogen Cunningham, Anna Atkins, Anin Astiti and Pablo Picasso. Variations of the technique have also been used for scientific purposes.
