I was covering the Badminton Horse Trials and was sat on the water jump. I remember photographing a faller, a Madeleine Gurdon who went on to marry Lord Andrew Webber, and knew it was a great pic. Two minutes later Princess Diana showed up and sat just to the left of us photographers on the water jump. Not only had I just photographed a dramatic horse falling picture but I now had Princess Diana in the bag as well, Job Done!
