In November 2013, National Geographic magazine invited photographers from around the world to submit photos in three categories: People, Places and Nature. They received more than 7,000 entries from over 150 countries, with amateur and professional photographers across the globe participating. You can view the winning images in a full-screen slideshow here in LensCulture.

Learn more about the contest, and even download the winning images as "wallpapers" or "puzzles" for your computer screens at the National Geographic website. The three top winners will be published in the print version of National Geographic.
