In addition to presenting danger, this large Pennsylvania mother black bear was looking for danger, a move that often includes a pause that gives a photographer time to carefully focus, compose, and shoot.
At this distance, the bear was not close to fitting in the 600mm frame. Keeping the bear's head in the frame is the primary compositional goal and shooting vertically with a sideways pose meant that a large portion of the frame was empty. Fortunately, the mamma bear's second-year cub was moving in and added interest to the empty portion of the frame.
As I had no control over either subject, this result depended on situational awareness along with a bit of serendipity. Time spent in the right locations increases the chance of serendipity.
While the bright gray background may appear studio-like, it was courtesy of a heavy morning fog between the subject and the distant background.
