National Geographic has launched their 2010 Photography Contest, giving one lucky shutterbug the chance to take home a prize that includes $10,000 in cash and a trip to Washington DC to attend the annual National Geographic Photography Seminar in January, 2011. But that's not all, as the winning photograph will also be published in an upcoming issue of National Geographic magazine, which is a dream come true for many amateur and professional photographers.

Entries are being accepted in the categories of People, Places, and Nature, and all submissions must be in a digital format and uploaded from the contest's homepage. You can enter as many photos as you would like, but there is an entry fee of $15 per image. The contest ends on November 30, 2010, so get to work on sorting through those photos.

In a few weeks time, the best submissions to date will begin to appear in web galleries online, and we'll all be allowed to browse them and vote for our favorites. Some of the best entries will also be made into wallpapers that can be used as desktop backgrounds and some will be converted into online jigsaw puzzles as well.

For an idea of what you're up against in this contest, check out a gallery of the best entries from last year by clicking here and then see who the overall winners were by clicking here. After perusing those galleries, I can see I have my work cut out for me.
