This is the Dupont Circle Metro station in Washington, DC. This photo was taken during a rainy afternoon last Thursday - the same place as yesterday's image. Although there are signs all over the place that say no photography, I went on the assumption they were talking about the always controversial use of tripods. So I sat photographing trains, people, and the cavernous walls of the station for about an hour. Metro police passed by, and I'm happy to say no problems. All photos were shot handheld at about 1/10 of a second. In this image I used a Lucis Art layer on the ceiling and a Nik Color Efex Monday Morning Sepia layer masked into the train.
