What is a photographic print made by placing objects on light sensitive paper and exposing it to light?
A photogram
How were photograms invented?
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. In a darkroom, or a darkened room, objects are arranged on top a piece of photographic material, usually photographic paper. When the operator is satisfied with the arrangement, the photographic material is exposed with light, usually by switching on an enlarger or other artificial light source. The material is then processed, washed and dried. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear grey.
How is the timer used along side the enlarger in the darkroom?
The timer is used to set the intervals at which the light is exposed to the photographic paper. After the timer is turned on, there is a switch that sets the exposure time. This can be put into milliseconds, seconds, or minutes. Often the photographic paper is exposed for around 15 seconds, though this depends largely on the quality of the negative, style of the photographer, contrast of the print, etc.
