Pentax K-1, 150-450 Pentax lens, f6.3, 1/640 second, ISO 200
I went to Yellowstone National Park in February partly to capture images of wildlife surviving the harsh winter environment. As I was driving on the road between Gardiner and Cook City in the northern part of the park, I came around a curve and saw a small herd of bison approaching from the opposite direction. I stopped my car, leaned out the window and captured this image. I used a long lens set at 450 mm and fairly shallow depth of field to isolate the lead, snow-covered bison in focus, and throw the background and snow flakes falling between me and the bison out of focus. After taking the image, the bison slowly trudged through the snow storm past my car.
