Two photos from Portland, Oregon illustrating the great differences in light and mood one may encounter in a relative short time.
(Click to enlarge) The Fremont Bridge, which carries I-405 traffic across the river, in a dense fog. Photographed from the Broadway Bridge just to the south. This is a color photo.
(Click to enlarge) A building on the east side of the river, in the Rose District. The golden light of late afternoon made it glow - the color comes from sunlight, not from internal illumination.
