The Steichen passage I was quoting in another thread, I thought would defend Moonrise as a good photograph...
"When the photographer has something in front of him, chosen with his heart and his mind, and when he has brought to bear all the experience he has ever had, then he's prepared to press that button."
That sure sounds like the Moonrise scenario.
"...the moment you press that button that's it, you're through. What you can do afterwards is very limited."
This must be where Ansel Adams proves Steichen wrong.
