Tsutsumi illuminates a model space of their own construction and photographs it. The resulting print is then illuminated and photographed again. Built up through this repetition, In progress (2023–) is an ongoing series in which the image is continually renewed through cycles of shooting and printing. With each iteration, new images are generated. At the same time, details that once existed are blown out to white and disappear. Accumulation and erasure occur within the same act. At each exhibition, the light and shadow that arise in the gallery space are photographed together with the works and absorbed into the next stage of production. An exhibition is not a conclusion but the beginning of the next layer. In Reframing 'In progress' (2024), multiple prints are layered at varying heights within the depth of the frame, causing the boundary between the light and shadow accumulated within the image and the light and shadow falling in reality to blur. In Exposed and Reappear (2025), light is directed from behind onto areas that had been blown out to white during the process of repetition, causing traces that seemed lost to surface once more.
