Of all the elephant photographs I've made over the years in Africa, this one is my favorite. As the sun went down in Kenya's Amboseli National Park, two foraging elephants drew ever closer to us. They moved at a trot, head to head, tusk to tusk, in perfect rhythm. As the warm light turned their grey hides to a reddish gold, they seemed to be smiling as they brushed past me. It was one of those rare opportunities to make a photograph when everything had fallen into place simultaneously -- an endangered subject, a perfect vantage point, and golden light to intensify the meaning of this special moment in time.
