It's not new. There are now a couple of generations of photographers work, big names, whose work has totally deteriorated. Some of it I scan and reprint when collectors have returned it to the artist or gallery after 15-20 years. I have to explain to museum curators and gallery people to this day that type C prints are junk. It is amazing how even now most of even the high-end galleries don't know the difference between dyes and pigments or good papers and bad ones. My friends who did a lot of color work in the 80s with C prints and 20x24 polaroids have seen entire decades of their work lost. There are some people who take the trouble to go back and have their color negs and chromes, or polaroids, scanned, but most don't, they just move on.
