While I agree that accurate labeling of prints is important ( I would not buy an inkjet print when looking for a platinum, for example, and be righteously pissed off if someone tried to pass an inkjet off as a platinum ), you are confusing meaning with methodology yet again. The method of making the print is quite secondary to the content of the image, 99% of the time. I don't respond to a photograph and want to look at it for hours, or want to part with my hard-earned cash to hang it on my wall, simply because it is a (type x) print. I'm not going to part with my cash to own a fine-art-silver-gelatin-landscape-print-by-an-ansel-adams-wannabe just because it's a fine art silver gelatin print. It can be the most well-executed print in the world with the highest degree of craft possible, but if the image content hits the snooze button, the craft behind it (and the accurate labeling of that craft, which is the primary marketing position of said photograph) is irrelevant.
Accurate labeling of the materials used to make the print IS relevant to the owner of the print insofar as that determines how to frame, mount, or store the print.
Going back to the other "truth" notion we've been tossing around here, IN CONTEXT, declaring the degree of manipulation in an image is either critically important or utterly unimportant except for marketing purposes. Where do you draw the line as to what is too much? Helicopter shark is incredibly obvious in the "too much" department, as is the photo I've used before of a T-Rex, a man, and a flying great white shark that's bigger than the T-Rex, looking over the edge of a cliff.
On the flip side, though, if I had cloned out the scratches on the side of the caboose in this image
(the ones beside the side window of the caboose, closer to the viewer) would it have made ANY difference at all in the "truth" of this photo, or your enjoyment thereof? No. The only time it would have mattered is if I were selling the caboose and represented it as having a perfect paint job. So context matters, infinitely more than some ideologically pure standard.
Where I feel like you're getting lost is the insistence on craft over content.
I do feel craft is important.
I do think people should place greater value on craft in their own work - craftsmanship is something to be proud of and exhibiting good craftsmanship is its own form of marketing.
I also think that we, as an analog-focused community, get entirely too caught up here in conversations around gear and technique to the detriment of image content.
