Photography is a means for capturing reality (which is usually considered unobtainable) by freezing it. You cannot hold reality but you can hold a photograph. Photography is not only a way of preserving the past but also a way of handling the present, with photographic images becoming more and more widespread in modern times.
Photography also means that we can see something before we experience it, and that takes away from the virginity and openness of the way we experience reality. Reality, in other words, is photographed before it is experienced.
Photography is not a mere copy of reality but rather a recycled copy. We consume photographs at an ever increasing rate and they are therefore consumed and need to be replaced. Meaning, the more we take photographs the more we need to take photographs, and this accounts for what is known today as the "pictorial turn".
