Are you going to answer questions straight out or continue going around in circles? Blah, blah, blah, blah.
Just provide the proof that film that has been frozen for 15, 20, 30 years (I've observed how your figures are now all over the place) is entirely useable and that the methods and means by which is is processed are available. You have not provided any proof, just bluff and bluster.
Regarding fine art. Oh please! How is this somehow entwined with film, and only film? Have you studied the realm of fine art? What branches throughout the realm of "fine art" rely solely on film? Photography? Really? I don't think so! I don't equate film, either its type, quantity, reputation or availability, with "fine art". Yet more nonsense being espoused by those thinking they've been there, done that and can thank film.
Your naivety is startling, truly startling. I don't think you've been in photography all that long, especially professional practice. Please just get on with photography rather than repeating how much film you've stuffed away for D-Day. And don't be so bloody rude and arrogant to assume of others, "if you're still alive" (presumably, we can wonder about you too?) we can stockpile! I think you need to shake out of your stupor, along with a few others.
