A few weekend ago, I had a chance to tour and explore the tunnels underneath Dupont Circle. Years ago, Washington D.C. had an extensive street car system, with lines that ran underneath Dupont. That system was discontinued in the 1960s, but the tunnels remained. In the 1990s, they were repurposed as a food court, which eventually failed. Today, they are an occasional art space and a neat place for photographers to visit and explore.
Obviously, I couldn't shoot this with film, so these photos are digital.
Camera: Fuji X100T with wide-angle conversion lens. In-camera monochrome filter.
