For his Layer Drawings series, artist Nobuhiro Nakanishi photographs the same shot at regular intervals, then prints them on glass and layers them into mesmerizing sculptures.
Via his site:
This series portrays changes that take place in everyday life, like the sun rising or ice cream melting. These ordinary events were photographed at regular intervals, printed on transparent film and assembled in sequence. Capturing the accumulation of time as a sculpture allows the viewer to experience the ephemerality of time.
We are all subject to the passing of time, yet each of us feels and perceives it in our own way. Time itself has no shape or boundary and cannot be fixed or grasped. When we look at the photographs in these sculptures, we attempt to fill in the gaps between the individual images. We draw from our physical experiences to fill in missing time and space, both ephemeral and vague. In this series, I attempt to depict time and space as sensations shared by both viewer and artist.
