That’s a quote from the legendary Robert Capa, and it appears at the beginning of “War Photographer,” which is a documentary about Jim Nachtwey, whose life and ideas are no less stunning than the beautifully grim pictures that have made him famous in the world of news photography. The film uses, to great advantage, footage from micro-cameras attached to Nachtwey’s cameras, so that you see what he was seeing in the field, and you see him as he was seeing these things. It’s a hall-of-mirrors effect that is remarkable, as are the first 15 minutes of the movie, in which you watch Nachtwey but don’t hear a word from him, and it doesn’t matter, because the editing is so sharp.
