'evoking a sense of humanity'

Yesterday's sessions ended with War Photographer, a film documentary about photojournalist James Nachtwey. I found it to be an eye opener not just for Nachtwey's stunning photos, but more so for his insights about his work. Certainly, covering war is one of the most dangerous things one can do -- yet, Nachtwey seems to have succeeded in capturing heartbreakingly truthful images.

Through it all, he has kept a level head. "The people I photographed were much more important than myself," he said in the film. This explains his success in being "invisible" in his documentation of people living in difficult conditions. He is not a paparazzi but a sensitive storyteller. The photos are not eye candy but they must be seen. In the film, he says of his photography, "We must look at it. We're required to look at it. We're required to do something about it." A long pause, and he continues: "If we don't, who will?"

One might describe Nachtwey as an advocate of the power of photojournalism: "The strength of photography is its ability to evoke a sense of humanity," he said. "If used well, it can be a powerful antidote to war."

Fittingly, Nachtwey has won numerous awards. In this TED talk, he accepts his 2007 TED Prize:
