Documentary Tech has a good article about the superb documentary Restrepo.
Roger Ebert says in his review: "It was filmed at great personal risk by the war photographer Tim Hetherington and the author Sebastian Junger (The Perfect Storm)..."
A couple technical notes:
One of the things that struck me is the way journalism, still photography and filmmaking are converging.
Sebastian Junger used a Sony HVR V1 and Tim Hetherington used an HDV Z1. Both are HDV tape cameras.
