Bussières' practice operates between photography and sculpture, using light as both subject and material. She works primarily with lumen printing, exposing silver gelatin paper to natural and controlled light for durations ranging from seconds to days. Light, time, and environment act as collaborators, producing unique surfaces that register atmosphere, contingency, and place. Gradations of blues, violets, pinks, and warm tonalities emerge from the chemistry of the paper itself. These works function as temporal imprints-records of contact between surface, light, and movement. Rather than depicting an image, the works stage an event. Each print embodies a specific duration in which human gesture and environmental forces converge, inviting sustained attention to perception, instability, and the passage of time.
