Flip through the pages of any issue of the National Geographic Magazine and you'll find eye-opening and evocative images - the best published anywhere in the world. Earning the "yellow border" is one of the most highly-prized accomplishments in photo-journalism. Yet even among these striking images, there are some that stand out as instant icons for our times. And what really set all of National Geographic Magazine's photos apart are the stories behind the photos. With flair, action, and behind-the-scenes footage, this one-hour special counts down the "best of the best" from the magazine that has won dozens of national magazine awards for photography. We're asking the editors to take a list that includes hundreds of amazing photos and whittle it down to just 10. As we do, we reveal the stories you haven't heard about the photographs. The program will include interviews with National Geographic Magazine Senior Photo Editor Chris Johns, as well as photographers and editors involved in everything from getting that perfect shot, to choosing the right photo.
