Solarigraphy


Solarigraph with the sun paths between July 2018 and May 2019 in a street at Valladolid, Spain

Solarigraphy is a concept and a photographic practice based on the observation of the sun path in the sky (different in each place on the Earth) and its effect on the landscape, captured by a specific procedure that combines pinhole photography and digital processing.[1][2] Invented around 2000, solarigraphy (also known as solargraphy) uses photographic paper without chemical processing, a pinhole camera and a scanner to create images that catch the daily journey of the sun along the sky with very long exposure times, from several hours to several years.[3][4] The longest known solarigraph was captured over the course of eight years.[5][6] Solarigraphy is an extreme case of long-exposure photography, and the non-conventional use of photosensitive materials is what makes it different to other methods of sun paths capture such as the Yamazaki´s "heliographys"[7]
