National Geographic Photo Contest 2010: Stunning User-Submitted Images

From National Geographic:

The 2010 National Geographic Photo Contest attracts thousands of imaginative and amazing photos from around the world. People can still submit their photos in three categories -- People, Places, and Nature -- until November 30.

Aside from submitting your own photos, get more engaged in the contest by voting or your favorites on National Geographic's site, downloading lovely wallpaper, playing one of the puzzles, and/or checking out past winners! The first-place winner in each category will receive $2,500, and have their winning photograph published in National Geographic magazine. One grand prize winner will receive, in addition to the first place prize, $7,500 and a trip to National Geographic headquarters in Washington, D.C.

We've featured a sampling of some of the submitted photographs that National Geographic is sharing with us exclusively -- from a night soccer game in Barcelona to a storm ripping its way across Argentina. Check them out and vote for which you think should be the winning shot!
