Solargraphy

I suppose it is too hot in Memphis for this. I built a pair of pinholes with the absolute tiniest aperture I could make. Mounted them on top of a building for a couple months and let them expose. The result? A hole almost burned through my paper and the paper crinkled and discolored. I am going to rework my plan this fall and try some winter exposures.
