It is already one of the world’s most iconic cities, but this incredible collection shows how much Paris has changed over the course of the past century. The collection, by French photographer Julien Knez, shows Paris in the 1940s against a backdrop of how the same places look today. Knez says he put the striking collection together to celebrate the 71st anniversary of the city’s liberation from Nazi control in August 1944. Here: Soldiers outside the Hotel De Ville in the 1940s.

Randy Scott Slavin's photography is surrealism based in reality. His work portrays land and cityscapes in a 360 degree view, a perspective closer to that of the human eye than a 2D photograph, he says. Slavin's "Alternate Perspectives" is a series of photographs of a single location or landmark pieced together to create a 360 degree perspective in a flat image. The results are whimsical, and occasionally eerie, scenes that reflect the portion and scale of Slavin's surroundings when he took the photo.
