Example: Alternative Photography- Lumen Printing

I recently discovered a form of alternative photographic printing called the Lumen printing process.

It's essentially a photogram made using the sun and a piece of moist organic material (ie: flower). The organic material is flattened against photo paper with a piece of glass on top, and then the sandwich is exposed to the sun (or UV light) for a period of time ranging from half an hour to a day. The volatile organic chemicals that are released by heating the organic material are responsible for making really funky colors on the photo paper.

After the exposure, the paper can simply be fixed using normal fixing and rinsing techniques (no development necessary).
