You might remember Matt Mawson from his great Coney Island series. This time he captures the Queensboro Bridge in New York City and its surroundings. I think the high contrast in these photos really helps make these rainy day photos come to life and gives them a gritty look.
This is a wonderful black and white photo of a street in Lodz, Poland taken by Marcin Stawiarz. The contrast created by making this a black and white photo is what makes it so great.
