THAT (displayed pic) seen in front of face: is the result not merely of having anticipated.. Seen!... and 'SHOT' aka pressed shutter release.
It only began there, and while the fiddly-bits of Ansel's day consumed aeons of (a lifetime) and new techno RAW etc. gives easier access to unprecedented Power to influence the final viewable result:

The 'dodging' and other aspects of Ansel's decisions: were about demonstrating much-More of "what was There if you had Eyes + a brain making infinite auto-corrections."
He was striving for bringing as much of that mind's-eye experience to paper as all his talents could manage.

That's Art, based upon n-skills and a fine mind. And the medium IS the 'message': you haven't experienced Ansel without seeing His Print (in suitable lighting also, etc.)
IMhO, Nothing that 'meets-the-eye' in some moment IS ever simply-transmissible. And I am unanimous in that
