Solarography & the Diet Coke Can

Read about the idea of shooting direct to paper and not developing it as a way of getting even longer exposures. This technique is called solarography and I believe was originally a way of photographing the movement of the sun. I put a piece of photographic paper into a diet coke can with a pinhole in the side, sealed it up and left it out for just over twenty four hours. The above image is the result. Even after twenty four hours it is still massively under exposed!
The paper is not developed, simply taken out of the can and scanned straight away. If left out in the light the image on the paper will fade away. There is no way of developing or fixing the image, you just have to keep it in the dark if you want to keep it.
This is really interesting, and I intend to try this some more.
