Photographer Paul Bussell presents here a selection of his series on big cats: Sumatran tigers, lions, clouded leopards and snow leopards. All in black and white, his stunning images feature these magnificent felines in a variety of poses; atop cliffs, cuddling together and splashing in water. This begs the question: just how did he manage to achieve these fantastic images? There must surely have been an element of danger involved in the creation of these works!
