"Human visual perception is a far more complex and selective process than that by which a film records. Nevertheless the camera lens and the eye both register images—because of their sensitivity to light—at great speed and in the face of an immediate event. What the camera does, however, and what the eye in itself can never do is to fix the appearance of that event. It removes its appearance from the flow of appearances and it preserves it, not perhaps forever but for as long as the film exists. The essential character of this preservation is not dependent upon the image being static; unedited film rushes preserve in essentially the same way. The camera saves a set of appearances from the otherwise inevitable supercession of further appearances. It holds them unchanging. And before the invention of the camera nothing could do this, except, in the mind's eye, the faculty of memory."
