John Berger quote

"I have said that a photograph bears witness to a human choice being exercised. The choice is not between photographing x and y, but between photographing at x moment or y moment. . . . What varies is the intensity with which we are made aware of the poles of absence and presence. Between these two poles photography finds its proper meaning. ... A photograph, while recording what has been seen, always and by its nature refers to what is not seen. It isolates, preserves and presents a moment taken from a continuum. ... Hence the necessity of our understanding a weapon we can use and which can be used against us." - John Berger
