I had the privelege of being able to go see the current exhibit at the Corcoran Gallery in D.C. last Tuesday with some colleagues: "WAR/PHOTOGRAPHY: Images of Armed Conflict and Its Aftermath."
It's a powerful show, and I recommend you see it, if you're able to. NOTE: IT'S ENDING THIS WEEKEND, SEPTEMBER 29th! SEE IT WHILE YOU CAN!
It is also a great overview of how we see war (and in some ways how we don't see it-- there were some very graphic images I'd never seen before, of casualties, military and civilian, which were probably originally withheld from the public). Click
