The other year, I decided to try solargraphy, and this was the result after 6 months exposure. The picture was taken using pin hole technique with a small piece of black and white photo paper, which was placed inside a 35mm black film canister. Then taped to the window frame outside. Photo one was a view of the rail line, photo two was from the rear of the house, and the final photo was from taken from the same place as number one, but at a different angle.
I love experimental photography, it has unusual results, especially the fact that I have used black and white paper and this was the result. This is how the finished items look, however, to stop them going black instantly, they have to placed in a bath of fixer so that no more light will affect it.
I intend to do a bigger one 1 day and leave it there for a year, looking into the sky showing the suns pattern or rise and fall.
