Not really
All of Ansel Adams' work happened in the darkroom, and was made with his hands - I don't mean dragging the film and paper through the chemicals - I mean an elaborate shadowing with the hands of the print as it is being exposed in the enlarger. It can take many seconds to expose a print - during this time a skilled photographer will often use his hands, or some other object, to lessen the exposure on particular parts of the print. It may take hundreds of attempts to get it just right - so the final print is a unique work of art and not a copy of the negative.
A good example is the famous photo of birch trees - another is the Moon over - is it Santa Fe? The copyright Nazis removed the good Ansel Adams net exhibits.
