I have a family membership at the Bronx Zoo. The gorillas are one of my favorite exhibits. I am amazed by their mannerisms and disposition. I am amazed with the reddish hair at the top of the gorilla's head, that came out more with saturation with adjustments in the photo's RAW settings. For this photo, I rented a 100-400mm telephoto lens, and captured this portrait at 400mm. This photo is not available for commercial usage.
