In the early days we were surprised and delighted with a photograph, as a photograph, just because we had not hitherto conceived possible any definition or finish that approached nature so closely... But soon we wanted something more. We got tired of the sameness of the exquisiteness of the photograph, and if it had nothing to say, if it was not a view, or a portrait of something or somebody, we cared less and less for it. Why? Because the photograph told us everything about the facts of nature and left out the mystery. Now, however hard-headed a man may be, he cannot stand too many facts; it is easy to get a surfeit of realities, and he wants a little mystification as a relief.
