I was just trying to see what, if any, evidence exists on vinegar syndrome affecting acetate-based film and at what kind of time interval.
I assume that what the likely life expectancy of acetate-based film is an important consideration for most photographers and if that life is beyond the need of most photographers then the fact that it may well not last as long as polyester may not be of much importance
Vinegar syndrome is a major problem for archivists - the people at the Vancouver archives have had to resort to digitization to help deal with potential image loss in respect to their extensive collection of negatives, including many Cirkut negatives.
