National Geographic's Most Incredible Photos

"Among its many wonderful merits, National Geographic places a particularly high premium on photographs; a few of those images, in turn, stand out from among the others as indelible icons of the cultures and eras that produced them. The documentary series National Geographic's Most Incredible Photos singles out several such photos and unveils the compelling stories behind them. This collection features three episodes from the series: Lava Hunter, Afghan Warrior, and Nat Geo's Top 10 Photos."
