Photographer Tokihiro Sato (born 1957), along with contemporaries Toshio Shibata and Naoya Hatakeyama, focuses on the shifting landscape of modern Japan. Using a 8 x 10 inch camera fitted with a darkening filter, Sato creates lengthy exposures in which he moves throughout landscapes, pausing periodically with a mirror that reflects sunlight back at the camera. The light is recorded, as are traces of his presence, but he himself is rendered invisible by his motion.
