Sometimes hinting at what's offscreen can be just as intriguing as what's on it. This is one of Winter's shots and one of the few pictures ever taken of a snow leopard. Winter says that if the leopard were on the left, his stare would have had less impact. Because he's looking offscreen, we're left to wonder what caught his attention. "If you shoot an animal or a person and they are framed to the same side they are looking out at, it creates a sense of wonderment," he says. That may seem like something a photography teacher would tell you to avoid, but this particular photo made Winter the BBC Wildlife Photographer of the Year 2008.
