the gorillas at the san francisco zoo are some of my favorite practice subjects. 1. a partial view of their exhibit and the entrance to their night quarters on the right... 2. the no. 2 male... 3. the no. 2 male lounging on a tree stump with one of the females... 4. the no. 1 male silverback peeking out from the night quarters... 5. ho hum! 6. i feel sorry for them. they're obviously bored... i'd appreciate any/all tips to improve my shots of these gentle giants. thanks.
