Digital BW, The Print

Peter's experience indicates exceptionally bad processing and/or
storage, and or profoundly bad personal luck. 

I have a collection of 35 and 828 film of various types going back to
1939 (my mother's home-processed Anscochrome)...none of it is
"deteriorating" though my father's Kodachromes from Korean War are
shifting colors (though not his earlier Kodachromes from Panama), as
are some of my own Kodachromes (though not my E4) from 1970-75. I also
have family negatives going back into the 1800s that are not
"deteriorating." 

I have however seen 8X10 negatives from WWII whose emulsions were
bubbling off. 

IMO one should take good care of one's negatives as long as is
feasible, counting on digital storage in the event people in the
future think there's a reason to retrieve our wonderful images.
