In 1984 I took some nice shots on Agfapan. In attempting to scan them recently, I get sketchy results. The negs are thin; they look faded. I printed one of the shots in 1984; it came out very rich looking. Is it possible for mono to lose quality over time? The negs have been in quality storage until last week. Here is one scanned frame. You will see the grain and low acuity, and this is not a huge magnification.
