Your Shot: A sneak peek at National Geographic's contest submissions

National Geographic magazine turned 125 this month, with an anniversary issue devoted to the power of photography. The magazine moves the birthday celebration off its pages with the October 1st public launch of a photo-sharing platform, Your Shot (NGYourShot.com), that allows photography fans to connect with photographers and editors around virtual assignments, get direct feedback on their work and participate in a unique photography-based community. One of the magazine’s young star photographers, Cory Richards, will usher in the month as lead curator of the magazine’s first assignment on Your Shot.
