David, I think I've already put it as clearly as I'm able to see it for myself.
I am not totally convinced that 'wet' photography was any the more pure; all those 'photographic' images made without cameras fit right in there, too, but their damage was very limited because it wasn't about to be transposed into other things quite as readily as digital trickery allows. I think you can't really put the wet pioneers into the same box as the digitists; those early guys were learning what the medium could actually become - its boundaries were not yet defined very clearly. As you know, several schools of photographic thought sprang up and were devoted to aping paintings, avoiding anything to do with paintings and then, finally discovering that photography wasn't painting all along, and that it had a very valid space all its own. In short, photography came of age.
Now, taking this outwith what I understand to be the meaning of photography (and no, nothing to do with drawing and light) but the art/craft of photography, we start to tread on marshy ground. When one takes the real away and, in its place, presents a construct, then I think things become spurious. And I see it respresented very well via Hollywood and the media: was a time photographers - often via Magnum or Globe - would be given freedom on film sets, and thus we have the visual legacy of those wonderful images by Ernst Haas et al. shot during the making of Marilyn's The Misfits just a year before she was no more.
Now, those pictures reveal a woman already in trouble, in all of her vulnerability, exactly as does Avedon's classic made at the end of a session when she stops playing the rĂ´le of Marilyn and shrinks back into being lost and afraid. Apparently, Avedon shot it knowingly for that reason, and, he claimed she understood and did not attempt to thwart him. And don't forget: at the same time as photojournalists were given access, so were the overlit studio PR shots being made and sent to salivating fans. Today, none of that, AFAIK, is allowed to happen: teams of PR and legal aides supervise, everything is vetted and retouched to hell, and what do we get? Absolutely interchangeable plastic dummies. That's my rather tortuously made point: there is real and there is bullshit. One either gets that point or one does not. I remember writing recently about somebody saying that he'd give every painting of Christ for one photograph of Him. I think we are on the same page, he and I. One honest Marilyn is worth every PSed actress and superstar you can name. How exciting that Jennifer Aniston hasn't aged a day since making Friends!
For me, that reality carries over into everyday photographic reality. Mess too much and hey, you get mess.
