Photograms.

A photogram is a fixed shadow of three-dimensional object on a light-sensitive material. There is controversy as to whether the photogram is it's own medium. Part of the scope of www.photogram.org is to strengthen the medial independency of the photogram as a shadow picture. Everybody know's the strange feeling watching for the first time his own body as a photogram on an x-ray. Sometimes the technique is also called "shadography" or "rayograph". This process can be easily re-created at home, in a darkroom the paper is briefly exposed to light and later developed.

Here are a couple of my experimental photograms we did in our college darkroom.
