This Year's Finalists In The Tenth Annual Smithsonian Photo Contest...

The Smithsonian Magazine has just announced the finalists in their 10th Annual Photo Contest.
Over 37,000 images were submitted by photographers in 112 countries.
The Smithsonian judges selected fifty finalists over the five categories. The Natural World, People, Travel, Altered Images and Americana.
As usual the photos are open to a public vote until March 29, 2013 and the Reader's Choice Award, it may be yours, will be announced with the winners later on in June.
Here are a few of my favourites.
You can see them all and vote here...
