How does the artist create these photographs with such strange light? A video made by Sato himself shows that they are exposed for a long time while he moves around with a mirror, stopping to direct the reflected sunlight at the camera lens.
Through this monotonous pepetition, the particles of light are brought onto the photograph. This procedure reveals that scenes which at first sight seem to be filled with poetic expression actually possess constructed spaces and structures. The light reflected by the mirror converges on the camera and the tracks of light link the camera with light particles. Looking just like a land surveyor, Sato walks around holding the mirror and measuring the interval between his location and the camera according to the path of the light. This is nothing other than the measurement of space.
