Among the most affecting and iconic works of photojournalism are those that capture the human experience at its extremities: war, famine, disease, torture, genocide. The best of these photographs reflect back to us our starkest human material, and bring into focus both the benefits and the costs of political events and policies. They give “a voice to those who would not otherwise have a voice [and] put a human face on issues which from afar can appear abstract or ideological.”

For various reasons, not many photographers operate in this space. One who does is James Nachtwey; he has produced an enviable body of work from our war zones and brought to light vital stories from around the world. He wanted above all to be a war photographer, “driven by an inherent sense that a picture that revealed the true face of war would, almost by definition, be an antiwar photograph.” Photography like his is much more than being at the right place at the right time — it requires a certain eye, a special way of looking at the world, which can recognize and distill a significant human experience into an image. Above all, it is a work of demanding intellect, honesty, and empathy.

Visit James Nachtwey’s website, read his bio, and hear his inspiring speech at the recent TED awards acceptance ceremony for 2007 (also explore other TED talks by some pretty smart people). I’ve chosen here a few of my favorite images from his website.
