I was attending a Photographic Society of America Int. (PSA) Conference, Sept. 2015. Yellowstone and the Grand Teton Nat. Park area are among my favorite Nat. Parks for photography. When in the area, I like to spend at least a week shooting in the Fall or Winter on snowmobiles. This image was made at Schwabacker Landing in early Oct. Tools for the day, Canon 7D mark 11 and Canon 100-400 IS f4.5-5.6 11 lens, hand held. My setting were f 8 for proper depth of field, 200 ISO at 50th of a second. I was able to make several images from different vantage points before he moved toward a prospective mate.
