Sato Tokihiro（佐滕时启 Sato Tokihiro）is a photographer, born in Sakata,Yamagata(Japan)in 1957. Sato is best known for his unique expressions of light and space and interpretations of performance and dance. Receiving his MFA and BFA in Music and Fine Arts from Tokyo National University of Fine Arts and Music in 1981,Sato was originally a trained sculptor, but decided to go with photography to better communicate his ideas. Recognized for his playful interaction of light,Sato uses a large-format camera for exposures that last from one to three hours,while he moves through the space creating points of light or illuminated lines drawn with flashlights or flashes made by reflecting mirrors. The results are detailed photographs interrupted by patterns of light. And because of the long exposures,Sato’s movements across the scene remain undetectable by the camera; the photograph captures his presence but not his image. Sato’s photographs are held throughout the world in public and private museums including the Museum of Modern Art(Saitama,Japan); Hara Museum of Art(Tokyo); Queensland Art Gallery(Brisbane); and Tokyo Metropolitan Museum of Photography.
