Rhino Attacks Elephant - Steve Winter

National Geographic magazine features the world's most stunning images, delivered every month and enjoyed by readers in the comfort of their homes. But Steve Winter, who photographed the August 2010 cover story "Grassland Kingdom," tells Boyd that photographers endure significant risk to capture images. He shares a story from his time in India's Kaziranga National Park, where a rhino attacked an elephant that he was riding while trying to photograph tigers.
