Susan Sontag, On Photography page 13

Eventually, people might learn to act out more of their aggressions with cameras and fewer with guns, with the price being an even more image-choked world. One situation where people are switching from bullets to film is the photographic safari that is replacing the gun safari in East Africa. The hunters have Hasselblads instead of Winchesters; instead of looking through a telescopic sight to aim a rifle, they look through a viewfinder to frame a picture. In end-of-the-century London, Samuel Butler complained that "there is a photographer in every bush, going about like a roaring lion seeking whom he may devour." The photographer is now charging real beasts, beleaguered and too rare to kill. Guns have metamorphosed into cameras in this earnest comedy, the ecology safari, because nature has ceased to be what it always had been--what people needed protection from. Now nature--tamed, endangered, mortal--needs to be protected from people. When we are afraid, we shoot. But when we are nostalgic, we take pictures.
