There are many herds of sheep on the fringes of the Sahara. We stopped for one that filled the road before us. A alert group of rams with very large horns create a wall here to keep the other sheep in check. I also used a 750mm telephoto focal length to make this image – the rams were very far away, and I wanted to make them as big as possible. They were the subject of the picture and I needed detail to create the incongruous “wall of horns” that keep the rest of the sheep in line.
