New York Times executive editor Bill Keller explains why:
They need a sustained line of sight to frame their photographs; a reliable source is never enough. And they cannot avert their eyes; they have to let the images in, no matter how searing or disturbing. Robert Capa’s famous advice to younger photographers — “Get closer” — translates in combat to “get more vulnerable,” both literally and emotionally.
He asks: “Why do they do this crazy work?” The editor’s answer: “They do it for the most mundane of reasons (to feed their families) and the most idealistic (to make the world pay attention) and the most visceral (it is exhilarating; it is fun) and the somewhat existential.”
