So you're off to Rwanda, Uganda or Congo to see the gorillas? You'll be taking a camera, then. You are also about to take photographs of one of the trickier wildlife subjects around: it's not a simply matter of getting close to the subject, but of actually getting sharp and clear photographs of something dark and hairy that lives in a fairly dark and hairy environment. So this is a short note, derived from my own experience and mistakes, purely aimed at helping you decide what to take and what to do when you get there.
