“Solargraphy” is a technique of taking VERY long exposures (up to a YEAR long) with a pinhole camera to record the daily tracks of the sun across the sky. Solargraphy differs from “normal” pinhole photography in that photo paper (the type normally used in a darkroom for printing black & white negatives), is used to record the image, not film. After such a long exposure, the resulting negative image is visible even without being processed with developer, stop bath, and fixer. The paper needs only to be scanned and the image inverted in Photoshop to produce a final positive image.

This is, needless to say, a long-term project, and I'll add images to this collection as they are made.
