Ever dream of becoming a photographer for National Geographic? Well, here’s your chance–sort of. National Geographic Traveler and Photo District News are co-sponsoring a photography contest called World in Focus. You can enter as an amateur or as a professional in any of six categories: Wilderness Photography, The Human Condition, Extreme Exploration, Urban Landscapes, Snapshots, or Open Series (photo essay). The deadline is August 21 of this year, although you can actually enter until September 7 if you’re willing to pay an extended entry fee. Although the prizes are nifty, one of the best reasons to visit this site is to see the entries that have already been received.
