Buffalo at Old Faithful, Yellowstone National Park
Dr. Arthur Tiedemann 

In late Autumn, my wife Sharon and I found this buffalo bull close to Old Faithful geyser. As he grazed peacefully, I took advantage of his preoccupation with feeding to get close and capture several images. I used a Hasselblad with 80 mm lens and Agfa Ultra ISO 50 color film.
