Zhang Liaoyuan, Light Changed by Image

Zhang Liaoyuan’s work marshals visual technologies to explore the visual structure and visual phenomenon of contemporary society. Light Changed by Image is a space that automatically modulates light levels based on RGB image data. He abstracts a film into three continuously changing data streams, then directly converts these into the opening angles of blinds on three windows, thus continuously changing the light levels inside the space.
