I think you, c6h603, and Tonopah Jim,
have come closest to the answer, what if anything can we really attribute to Ansel, but rather a continuum of concepts prevelant in some circles even during the "hey day" of pictorialism.
Who first showed the splendors of Yosemite territory.......
"Mid-nineteenth century wet-plate photographers, C.L. Weed, Carleton Watkins, and Eadwaeard Muybridge, made the ardous journey into what was then unsurveyed territory." Watkins especially, several expeditions with mammoth plate and stereo cameras.
"Adams himself recognized those precedents, claiming allegiance to them as a way of rejecting his immediate pictoralist inheritance."
"Straight" photography was being discussed as early a 1901 by Charles Caffin-part of Stieglitz's early circle.
"Adam's early silver prints, (which he called "Parmelian prints") have a small, self-consciously arty look to them; it was only in 1930, the year Paul Strand showed Adams his photographs, that Adam's pictures began to acquire the dramatic contrasts and expansive scale of his mature work. Throughout the 1930's and the 1940's he worked in close proximity to Weston, whose more abstractionist dramatic style no doubt, strengthened Adam's commitment to purist practice."
" Pre-visualizing"
"A similar desire for purity may lie behind his almost fetishistic concentration on craft, which in the 1930's led him to develop a systematic procedure for "pre-visualizing" the final printed image while the exposure was being made. Called the Zone System, it enabled Adams to adjust his exposure and development times to produce negatives ideally suited for enlargement--and, most important for Adams, negatives that contained within them the germ of his original "vision" of the subject."
*"Adams was not the first photographer to place a high value on visualizing the final image in advance,any more than he was the first to swear allegiance to sharply focused and finely detailed prints (his friend Edward Weston, for one, preceded him on both counts), but he was the first to combine the science on sensitometry with the aesthetic of the expressive photograph.........."
"Adams drew upon the already existing aesthetic of the Equivalent, as conceived by Alfred Stieglitz. Stieglitz held that photographs, besides being documents of what they are of, are expressions of something else-that something else being the vision or feeling of the photographer."
The true question is, what then is the meaning of Adam's vision of the natural world--or "for that matter, any clue as to what his unmatched technical brilliance allowed him to express."
"Throughout his life Adam's refused to speak about the meaning of his pictures--preferring, presumably, to let them speak for themselves. But if Adam's pictures are expressive, as he made clear he intended them to be, the criticism of modernist photography has yet to describe what they are expressive of.
If they are equivalents of the artist's deepest feelings, what are those feelings? As the photographer Robert Adams has written in regard to Minor White's imagery, "Sooner or later, one has to ask of all pictures what kind of life they promote."
"Today these efforts at getting to Adam's importance seem not unlike the kind of evasions ambivalent critics sometimes undertake..... One can search all the panegyrical commentary on the photographer's work and not find a single description of the meaning of Adam's vision of the natural world--or for that matter, any clue as to what his unmatched technical brilliance allowed him to express."
"The silence, coupled with the absence of any body of criticism that takes issue with the work, is what has left Adam's place in the art of this century suprisingly unsettled."
A book recommended on Apug forum several months ago in another post on what good books on photography one should read contains the above quotes.
The book, Crisis of the Real-Writings on photography since 1974 by Andy Grunberg" (see pages 34 and 35)
C6h6o3, I actually agree with your humble and unbiased pure baloney opinion and also with Tonopah Jim's B.S. opinion. Minor also got into the "equivalents" lets not go there.
As always thanks to all apugers, and Oh what fun.
