What about the Grand Tetons & Snake River?

Excellent question.

Check out the first image in this sequence from the Adams Gallery website.  It's a 1942 photo of "The Tetons and Snake River" from the Gallery's Ansel Adams - America's National Parks slideshow.

Now, check out this image from DOI.gov.

It goes without saying that they're pretty similar.  One might easily confuse the two, perhaps opining that the only difference was one of burning and dodging (allowing more or less light to various regions of the original photographic paper during the printing process) or (in our digital world) a bit of Photoshop.

Not true.  Check out the clouds.  The sky is materially different, not just tonally tweaked.  See the little T-shaped darkness, just above and to the left of the central peak?  It's not present in the Gallery's image.

Now, before the Photoshop fans get in an uproar, I'm perfectly aware that any modern image manipulation software could easily be used to swap clouds; however, let's all agree that neither the National Archives, nor the Adams Gallery, would be a likely suspect for such behavior.  So, once again, what we have are distinct images of the same subject.

The Gallery's image is triumphant, with the sun's glow illuminating the peaks and snow, "grandly" if you'll pardon the pun.  As for the National Archives/Interior image -- well, I can't help but think, "It Was a Dark and Stormy Night."

Mea culpa.
