San Francisco/Bay Bridge Night: "San Francisco and the Oakland Bay Bridge from Treasure Island. The two parts of this deliberate double exposure were separated by more than an hour; an initial ten-second exposure provided by the twilight backdrop; a subsequent six-minute exposure being required to capture the blaze of city lights. Double exposing in this fashion allows one to preserve a host of architectural detail which otherwise would be lost in the shadows. Below are a closer city view and detail within the city, as well as a zoom of the bridge with a close up of the far right tower."
