My photographic 'skills' probably haven't helped There is little natural light in the public viewing area; all the light in the den comes through the large windows you can see here. It's probably OK for the gorillas, but makes things difficult for photographers. On the orang side, near the door to the house, it can be hard to see the orangs on the upper area because of reflections. A companion in a dark coat standing at the end of the window to block the light is useful!
