This shot is clearly all about anticipation—and it's so gracefully executed that it's easy to overlook the technical mastery at work. Each of the onlookers is perfectly framed between the slats of the railing; that's where the photographer put the focus, so we'd initially catch their upturned eyes. From there, our gaze follows up the sweep of the stairs to a perfectly timed moment just as the bride takes her first step into the wedding day.
