I recently got the old enlarger out and rolled up a couple of rolls of FP4 that is over 15 years old. I also shot a new roll of FP4+ as I still have a 30m roll of the old FP4 so before I decided to use it I wanted to test it. Both rolls were shot in the same camera, on the same day (within 1/2 an hr of each other) aimed at the same objects. They were then developed in a twin reel tank in Ilfosol S (at the same time). The resulting negatives are almost identical, with the old ones slightly lees dense. Now I've got 30m of FP4 to use :) click, click, click....(posted 9413 days ago)Also, at the orginal msg was posted awhile ago, what happened?
