For close to four decades, Japanese artist Tokihiro Sato has been experimenting with long exposure photography. Specifically, he explores ideas of tempo­rality by entering his own frame and creating tiny points of light or illuminated lines to record his movements through space. Sato records his movements through lengthy exposures that typically last between 1-3 hours. He shoots both at night, with minimal light, but also during the day, in which he equips his camera with a darkening filter. When shooting in daylight, he flashes a mirror at the sun, reflecting its light into the camera lens. At night he “draws” with a small flashlight, creating eerie scenes punctuated by tiny pinpoints of light that record track Sato’s movement, but not his physical form.
