Walking the Line, photo by Harold Davis. View this image larger.
On a harbor bridge, I photographed the Moss Landing power plant. As I packed up to call it a night, I turned around and noticed the pattern of lights on the bridge—and the apparent line, mostly formed of shadow, dividing the sidewalk from the road.
I stopped down for good depth of field so the foreground and background would both be in focus.
Exposure data: 50mm, 20 seconds at f/20 and ISO 200, tripod mounted.
