This Polacolor 59 sheet film expired in November 2000 (!) There is still enough developer in the pods. Film speed went down from 80 to 20 ISO. Developpment time is now 3' instead of 1' There is a lighter zone across the mid section of all photos that was already there when I bought the film in 2002.
Film was stored in a cellar at constant temperature but not refrigerated.
