I often find myself checking out the White House Flickr stream, partly because I like Pete Souza’s photography, and partly because Souza uses the same camera and similar lenses to me which makes me curious about his shots (and Flickr posts much of the metadata so the nerds can check out lens, aperture, etc.)

I also find that on the White House Flickr stream, one can find really candid and interesting photos. For example this one, where the Park Ranger at Grand Canyon is clearly holding the President’s ear while the Obama kids are bored out of their skulls, hunched over in the hot sun with that “dad, can we just go now” body slump.
