I saw the same video. The photographer was, in fact, David Burnett, the person liked to by Doug.
I, too, have a 4x5 Speed Graphic and it's great fun to take it out doing news-type photography. I've wandered up close to the action just as I did when I was a TV news photographer, and, with the Speed, no one says a thing. I don't know if I look official with the camera - or crazy.
