One thing I better appreciate after Saturday is how candidates intuitively know where the cameras are, and how they monitor their expressions (or not) given the immediate of focus of attention and particular paths-of-sight.
At first, I was frustrated about my position on the extreme right flank. What it afforded, though, was an “out of view” angle. The first shot is representative of many taken while Kucinich was speaking — especially that look from Obama. Although Hillary’s expression here seemed one of amused good humor, these images might potentially be captioned: “Hey Dennis, are you on crack?”
