Craig that was refreshing, when I listened to those guys and how they felt about letting your audience becoming part of the scene that you are filming it really drives the point home, we have the luxury of having an on screen monitor to frame and get the shot, initially these guys were doing it blind.
Tripods have their place but they are not an absolute for good filming, these guys looked beyond that scripted look that event cinematographers need.
We take so much for granted. The editing was a nightmare to sync the audio of Kennedy's speech to the video. Although those cameras were "portable" they weren't light.
