In this short audio slideshow by the BBC, three AP photographers - Horst Faas, a two-time Pulitzer Prize winner most famous for his work during the Vietnam War, Santiago Lyon, AP's current global director of photography, and Oded Balilty, an Israeli who won a 2007 Pulitzer Prize for breaking news photography - talk about the emotional power of the still image, and their thoughts on the future of traditional still photography in the age of broadband.
