More interesting than the horizons is the concept that these images are worth a lot of money. Of course, they are worth whatever someone will pay, which is apparently a ton of bucks. Aren't plenty of Ansel negatives available for study (to proper researchers)? Adams shot A LOT. I would imagine thousands, maybe tens of thousands of his "slides" (as the newscast calls them) exist. And Ansel is no longer around to print them. I see it a little like finding Picasso's paints or perhaps marble Michaelangelo might have planned to sculpt. A painting or statue might be in them, but it will never be an original completed work by the master. Modern prints from people who worked closely with AA are available today and worth a lot less than a million dollars. I'm not discounting the value of the find (would love to have made it myself), but I don't understand the economics that would make it seven figures.
