The stunning photograph of two bison silhouetted in Yellowstone National Park’s winter morning sun was captured by Art Wolfe of Seattle, WA, who described it as, “perfectly backlit bison standing on a small rise in Yellowstone’s Lamar Valley.”
“Rising at dawn and braving the -30°F temperature I was able to catch the first rays of the morning sun,” he explained. “The bitter cold of a long winter’s night had left the animals encased in a mantle of thick frost. I had scouted the area the day before and had seen the herd of bison. They had bedded down there all night and now were standing and trying to shake off the cold as the sun came over the horizon. These are the serendipitous moments I wait for as a photographer. I shot this in the days of film, so I didn't know until I got back to Seattle and had the film processed if I had been successful or not.”
Wolfe got the February 2000 shot using a Canon EOS-3, EF70-200mm lens set at f/16 for 1/250 sec. using Fujichrome Velvia film.
