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.
