““The photograph not only stops time, Benjamin argues, but also works to project the future out of the past. The photograph is a forward-looking document, so to speak, anticipating a future viewer who will recognise in it a spark of contingency that cannot be contained to one temporal moment. As Benjamin puts it in his "Little History of Photography": "No matter how artful the photographer, no matter how carefully posed his subject, the beholder feels an irresistible urge to search such a picture for the tiny spark of contingency, of the here and now, with which reality has (so to speak) seared the subject, to find the inconspicuous spot where in the immediacy of that long-forgotten moment the future nests so eloquently that we, looking back, may rediscover it.””
