This brilliantly composed photo by Patrick Mackin comes from Chicago and shows a doorman looking for a cab in the rain. As someone wrote in the comments, the photo is reminiscent of an old movie.

Patrick took the photo in June with a Canon EOS 20D. He used a shutter speed of 1/80th of a second, an aperture of f/9.0, a focal length of 46 mm and an ISO setting of 3200.
