A photograph made without a camera? The idea seems almost impossible to most of us (unless you've had the chance to play around in a darkroom). A photogram is by placing objects directly onto the surface of a light sensitive material (like photo paper) and then exposing it to light. The result is a negative image of the items. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear gray.
One might remember the school day experiments of placing random leaves, keys, etc. as relatively simplistic. However, amazing works of art have been created using this technique.
Here we have a small example of images created that deserve recognition in this under appreciated photographic technique.
