Ansel Adams once said:
‘But I would never apologize for photographing rocks. Rocks can be very beautiful. But, yes, people have asked why I don’t put people into my pictures of the natural scene. I respond, “There are always two people in every picture: the photographer and the viewer.” That usually doesn’t go over at all.’
Which is — actually — quite profound, once you think about it. Did old Ansel read up on contemporary French thought or something?
