Photograms are early photographic images created without a camera by placing objects directly onto light-sensitive material and exposing it to light. Henry Fox Talbot, who coined the term "photogenic drawings", was an early pioneer of the technique in the 1830s. In the 20th century, artist Man Ray experimented extensively with photograms, which he called "rayographs", using unconventional exposures and object placements to create surreal images. His rayographs were not fully appreciated during his life but are now considered masterworks of the photogram technique.
