'Interior Fragment' choreographs three shafts of light, captured over nine months, into a single image. Working with light over time, I traced the sun’s movement through interior space, revealing temporal rhythms shaped by natural cycles and weather. Light became both subject and structuring force, authoring angles, reflections, and shadows. Presented as a reflective acrylic screen, it mirrors the present and filters the world in red, evoking the darkroom’s controlled conditions for seeing.
