Picture of principle

Generation of a Photogram: A spatially extended light source (1) illuminates objects (2 and 3) that are placed directly in front of a photosensitive film. Depending on the object's distance to the film their shadows look harder (7) or softer (5). Areas of the film that are in total shadow (6) stay white, areas that are fully exposed to the light (4) are blackened.
