The photo was taken using a Canon 5DM4 with a Canon 100-400mm f4L IS II lens set at 200mm at f5.0, 1/100 second and ISO 400 mounted on a monopod.

The photo was taken at the Cincinnati zoo and began as a full body photo. I cropped it because of his expression. I think he was just expressing his opinion of his companion's activities at the time.

I specifically boosted the blacks and whites to make the photo more menacing.
