You can enter as many as 35 photographs in up to five different categories (Americana, the Natural World, People, Travel, and Altered Images). Cash prizes will be awarded, and some of the winners will be published in the magazine and put on display in the Smithsonian Institution in Washington, DC.
The entry deadline is December 1, 2011 at 2:00 pm EST (this Thursday), so you'll need to hurry to enter.
Here's the contest link. Good Luck!
1. Are you a good photographer?
2. Have you ever entered a photo you took in a contest?
3. What was the most recent contest you entered?
