Every year, the National Geographic Photo Contest receives thousands of entries (for the 2012 edition, they got over 22,000 in all), representing the work of talented photographers from over 150 countries.
But only a few can win the contest. Here they are.
The overall grand prize winner was the pic at the top of this post. It's a shot of a tigress named Busaba shaking herself dry at Khao Kheow Open Zoo in Thailand, and it was taken by Ashley Vincent of Chonburi, Thailand.
Her shot won First Place for Nature Photography, as well as the Grand Prize, which includes $10,000 cash and a visit to the National Geographic headquarters in Washington, D.C.
