[Leica] So much for "film is forever"..

[Spencer Cheng]

Mark,

Frank is correct. Many of the degradations will not be noticeable. Don’t assume because you can’t see it, it didn’t happened. If a red pixel changes very slightly within a red blob of about 100,000 red pixels, are you going to notice?

Unless you diligently created data integrity checksums for every single image since day 1, you are not going to know when a ‘1' bit flipped to a ‘0’.

Regards,
Spencer
