Is that what you believe, or what you think should be true?
I just ask because that would imply that a collector or museum only cares about the final image and therefore places the same value on a JPEG shared on Dropbox as a print made by Ansel Adams. I don't know much (anything) about how museums decide what to purchase, but I'm guessing provenance plays a role in certain purchases?
Tell me how many hours Cartier-Bresson spent slaving over a print that he couldn't quite get right....
As others have said, if the viewer didn't know how much effort was put into a shot, would the viewer actually care
