Danger was all around me. They were closing in: pushing me, tugging at my legs, herding me, all sizes and ages, and all with a gleam in their eye. Usually I shoot alone. But that’s impossible at the zoo. I was in the midst of a dozen families of giggling kids shrieking at the site of huge bears playfully charging the windows of the underwater viewing room of the polar bear pool. I concentrated, trying to catch the bears as they darted past the windows, not knowing which of the five portals they might go to, trying to get a clear shot without hands slapping at the glass, and trying not to trip over kids or the armada of strollers. I also didn’t want to hog the view. So I stepped back and shot from behind the little mob, holding my camera overhead. Pretty soon I was giggling along with everyone else as the bears dove, tumbled, and bubbled about to the delight of their audience. Sure I missed some shots but it only takes one. And this one was it.
