Summary

Description
Generation of a Photogram: A spatially extended light source (1) illuminates objects (2, 3 and 9) that are placed directly on a photosensitive surface. Depending on the object's distance to the film, the shadow looks harder (7) or softer (5). Areas of the film that are in total shadow (6) stay white; they become grey (8) if the objects are transparent or translucent (9); areas that are fully exposed to the light (4) are blackened.
