On the first day of lockdown I began making solargraphs. Solargraphs are made with simple pinhole cameras using photographic paper instead of film. They record the changing path the sun takes across the sky. The paper negatives are not processed in chemistry but scanned and inverted digitally. The colours produced are unrelated to the scene photographed and comes from the appearance of finely divided metallic silver growing on silver halide grains. The photographic paper came from my collection, some of which belonged to my grandfather, who inspired my interest in photography. I’ve made about a hundred solargraph cameras since the beginning of the lockdown, from a variety of objects, many of which are still recording the sun’s path. All of these solargraphs were made within the boundaries of my suburban home.
