History, they say, is written by the victors. That has made documenting conflict, stretching from a small New York gallery more than a century ago to that cell phone in your pocket today, as much a part of war as the bullets, blood and boots it captures.

One thing quickly becomes clear to anyone who hasn’t spent time in a war zone: it gets pretty boring, pretty quickly.
