A photographic print made by laying objects onto photographic paper and exposing it to light. The technique of creating photographic prints without using a camera (photograms) is as old as photography itself – but emerged again in various avant-garde contexts in the early 1920s. Artist Man Ray refined and personalised the technique to such an extent that the new prints eventually carried his name ‘rayographs’. Art Terms.
