Here's a great set of double expsoures by Andre de Freitas. I find double exposures extremely fascinating. It gives a glimpse into two completely separate but intertwined worlds. Whenever I see them, I try to imagine what went through the photographer's mind when combining these images. I am especially curious about the first image in the set. It feels like there is a beautiful tale waiting to be told by this image.

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.

Some seriously cool aerial shots by 500px user Roof Topper. I especially like the perspective of the first photo. It takes some serious guts to sit on the edge of a tall building like that.

Epic. That is the one word I would use to describe this series by Damien Vassart. The combination of the crisp edges of the towering glass buildings with the fluid and organic movement of the clouds is an epic photo combination. The use of black and white creates a stark contrast between the buildings and sky, and also amplifies the amazing reflections in the glass.

Thomas Birke's urban photography really makes cities come to life. His photos give a preview of what life might be like in the future. To portray this, he takes photos of densly populated areas and tries to show at least 1,000 people and their traces in each picture. By capturing illuminated windows and light streaks of vehicles, you can see the footprint of urban environments. I highly recommend viewing his photos in full resolution to truly get a sense of what he is capturing.
