Arch Shadows

Gateway Arch, St. Louis, Missouri
Photograph by Tom Atwood
This photo was taken during the winter as low clouds moved in above the arch at about 9:00 p.m. The unusual shadows on the clouds were caused by 44 floodlights at the base of the arch, shining up. A tripod was used for this 13 second exposure, aperture: f/13, ISO: 100, focal length: 18 mm.

And what other processing did you do to the photo if any? Jon Montgomery

I did run this through Lightroom 2 - but other than boost the "vibrance" a bit, and maybe the exposure - nothing.
