Solargraph

A solargraph is a long-exposure photograph that captures the Sun's path across the sky over extended periods, often weeks or months. Utilizing a simple pinhole camera, such as one made from an aluminum can lined with photographic paper, solargraphs record continuous solar trails, revealing the Sun's movement and seasonal changes.
