'Working with a wide-angle lens from a cage in a river in lion territory is an abnormal way to spend the day, and a very low percentage way to take a photograph of note. Lions do jump, but it is not common and even when they do, there is little chance of a camera catching the leap well. A retrospective of my files would suggest that in 10 years I have only had two successful days. This January I had my second moment that transcended. Nikon has made my life easier over those years with the super-fast D5 camera, but most of all, I want to thank Kevin Richardson and his sanctuary - without whom this type of image could not even be considered.'
