What is a Photogram / Rayograph ?
Photograms or Rayographs are camera-less images created by placing objects on a photo sensitive surface and exposing them to light. Where the object touches the surface it will protect it from the light, leaving a white or pale grey impression. If light is able to get underneath the object the surface will change in tone. If not it will turn black
Anna Atkins created photogram-like images using paper that could be exposed in sunlight and developed and fixed in water. Photograms/Rayographs are the result of experiments in the darkroom where chemicals are used to activate the image which is finally washed in running water. |

How do you make a photogram?
First you choose some objects. You arrange the objects on a light sensitive photographic paper. This is then exposed to light for a few seconds. The paper is then taken over to the wet area of the darkroom and soaked in a series of chemicals.
