World Press Photo recently posted a series of videos on their site showing interviews with this year's award-winning photographers as they describe the stories behind their photographs.

I was particularly intrigued by Platon as he describes the stressful buildup to his portrait of the Russian president Vladimir Putin for Time magazine's Person of the Year cover story. Platon's portrait is rumored to be the only formal sitting that Putin has ever done.
In addition, the interview with the Dutch photographer Pieter ten Hoopen about his story on the mythical Russian town of Kitezh ("The Invisible Town") was revealing and poignant, as I was an admirer of this body of work from the get-go. His words about bringing a personal style and voice to journalistic storytelling should be thoughts well-taken in photojournalism circles.
Lastly, definitely worth checking out too is John Moore's detailing of his definitive photos from the controversial assassination of Benazir Bhutto and his experiences of being there at the exact time of the explosion.

Be sure to play w/ the little magnifying loupe, which allows you to zoom in and examine the fine details of the images.
