51.64408° N, 0.01862° E is the result of a two-year experiment in solarigraphy, created with a handmade pinhole camera installed in Epping Forest. From the Summer Solstice to the Winter Solstice, and back again, between 2023 and 2024, the work records the slow, imperceptible passage of time through continuous six-month exposures. Solarigraphy, a form of long-exposure photography, observes the trajectory of the Sun across the sky by combining the elemental simplicity of analogue pinhole practice with digital processing. Inside the camera, light-sensitive photographic paper captured the unmediated descent and ascent of the Sun’s seasonal arcs. No lenses or filters intervened, only raw sunlight, 93 million miles away, inscribed its path directly onto the paper’s emulsion. The resulting paper negatives remain unfixed, still vulnerable to light, since traditional darkroom chemistry would erase them. Instead, they were carefully scanned and digitally inverted, preserving the traces of celestial movement and revealing images that hover between analogue fragility and digital permanence.
