With film manufacturing having gone through the doldrums in the past 15 years or so, there was, as exists today, many a discussion on how to treat expired film. There's even an ongoing thread right now of someone wondering how to best develop TMY shot back in 2006. And then we have Vivian Maier, who didn't develop the vast majority of her shots; they only being developed relatively recently (and maybe still ongoing). I recall when I first heard about this seeing all the of unexposed rolls of film, and how it was being catalogued and such before developing. I don't recall who was doing the developing. But I do find it interesting that they have been able to perform the developing DECADES after the fact, wherein I would have to imagine the film was not stored--at least not always--under ideal conditions. The images I've seen (and granted, I do not know if these were developed long ago or relatively recently) show no signs of fogging or other issues one would expect with film that has been sitting around for so long. Does anyone know what special procedures, if any, were taken in more developing?
