Photographer: Kirk Johnson of Alexandria, Virginia.

A quiet afternoon (before the afternoon rush hour) at the South Capitol metro train stop in Washington DC. Took a series of photographs of this commuter train as it was coming out of the tunnel. I loved the way the light scattered, dancing across the walls, ceiling, and tiled floor. The picture has an almost eerie, foreboding feel to it.

Photographed with my Samsung Galaxy S3 Smartphone: Aperture priority, average metering, 1/15 sec shutter speed; f/2.6 aperture; ISO 800, 3.7 mm focal length.

Postprocessing using both Adobe Photoshop CS6 and Topaz Black & White Effects.

Amazing what one can capture from a smartphone/iphone.
