While cleaning up my studio I disocovered I have about 40 rolls of Ilford FP4 and Agfa 100 120 film that is anywhere from 2 to 4 years old plus two packages of 16x20 Agfa MCC 111/118 (unopened) two 1/2 years old. Everything has been stored in subdued no-light conditions and at room temperature or a littel cooler...is it safe to say this material is still usable...
