Photography is a medium of still images; it cannot create the illusionof motion in the manner of film, video or animation. The static nature of thephotographic image, however, has never prevented photographers from aiming torepresent motion. Rather than capturing the moment, they are often preoccupiedwith expressing movement and the passage of time. Fragile moments may be sweptaway by the momentum of movement, but this is not a given in photography,considering how movement itself is not a self-evident possibility for themedium. It is thus always a challenge to represent or convey motion—but also asource of creativity in diverse genres of photography.
