The changing color of daylight is recorded at different intervals of time using a piece of white sailcloth attached to a camera lens. The resulting photographs are cropped to vertical strips, then assembled to make one print; a portrait of the light in one place, in one timeframe.

At the base of each strip, small numbers indicate the time of day for a given frame. Sunrise and sunset times are marked when relevant. Titles indicate the location in longitude / latitude coordinates.
