Don't give up hope yet. I recently developed some film that had been exposed at least 11 years ago, and the negavives came out near normal. I over-developed about 10% in ID-11. I guess my quanta had not wiggled... I do not remember how I developed the old Agfa films way back when, but I believe that the technology involved in the film was noting earth-shattering, and that old fashioned developers should work normally. I vaguely remember that development time depended mostly on film speed.(posted 8714 days ago)
