Radnitzky was a photographer, painter, and filmmaker better known in the art world as Man Ray. After forming the New York Dada group with Marcel Duchamp in 1917, he moved to Paris and became associated with the Surrealists. By placing objects on light-sensitive paper and exposing them to sunlight, he created “cameraless” pictures called “rayographs.” He later turned to portrait and fashion photography, extensively documenting Parisian celebrities.
