Thanks very much for this excellent article. The photographs are superb. I don't know how many people would have had the experience to appreciate this, but photographing rhinos is both difficult and dangerous. To get such high quality images requires a special level of skill and experience. Back in the late 1970s I was trying to photograph a couple of rhinos in one of Tanzania's northern game parks, for the tourist corporation. Sure enough one of them charged at us, even while in the car some distance away. Fortunately our driver knew how to handle the situation, but it was a frightening experience as the animal came extremely close to goring the vehicle. Could have been a big mess.
