If we consider the difference between William Henry Jackson packing in his camera by mule, and the person stepping for a moment from his car to take a picture with his Instamatic, it becomes clear how some of our space has vanished; if the time it takes to cross space is a way by which we define it, then to arrive at a view of space 'in no time' is to have denied its reality.

Timothy O'Sullivan was, it seems to me, the greatest of the photographers because he understood nature first as architecture.

Little wonder that we. . .find the old pictures of openness - pictures usually without any blur, and made by what seems a ritual of patience - wonderful.
