History
How does a photogram make an image without a camera?
A photogram records the shadow and transparency of objects placed directly on light-sensitive paper or film.
The V&A defines a photogram as a photograph made without camera or lens. Objects placed on sensitized material block or filter light, leaving different tones once the material is processed.
Because object and support touch
Because object and support touch, the result records outline and transparency rather than perspective from a viewpoint. Artists have used the method to explore shape, scale and material presence; it is not a blurred or primitive camera picture.

A photobooth captures faces through a lens from a fixed position
A photobooth captures faces through a lens from a fixed position. A photogram bypasses the camera altogether, giving a useful comparison between photographic image-making as projection and as direct contact.

Objects shape the photogram’s silhouette
A photogram’s shape depends on what touches or sits above the sensitive surface. Transparent objects can transmit partial light, while opaque ones block it, creating different tones after processing. When looking at a contact image, ask what physical object may have formed its silhouette before assuming that every photograph depicts a camera viewpoint.
