Capturing the Sun’s Path: Exploring the Art, Science, and Chaos of Solargraphy

Solargraph cameras are a fascinating way to capture the changing sky conditions and movements of the Sun over time. These cameras consist of black and white photographic paper sealed inside a cylinder with a tiny pin hole drilled into the side. They are then placed in a secure location where they remain undisturbed for days, weeks, or even months at a time. The duration for which the camera is left to record is at the discretion of the photographer, who may choose to capture as little as one day or an entire season.
