Baboons, despite being the most evil of all apes, are quite photogenic, with eerily human-like eyes and looks-like-a-smile-but-it’s-not mouths. Dithering about processing this chap, to colour swap or not? Either way, I’m glad that viewing glass at the zoo is thick, even though it does make taking photographs harder!
