This film is probably about a year or more old, possibly bordering on 1.5 years old since exposed. The XTOL I'm using (1:1) was mixed in Feb, but put in 1qt dark plastic containers, topped to the rim, sealed tightly and left unopened. According to Kodak, this should not be a problem. I'm getting reasonably thin negatives. I started out at with a development time of 4:45, and am not at 6:00 at 75F in my Jobo, and they are still thin, so I'm going to 6:30. Something is definitely amiss here...as my typical Neopan 1600 time is 4:45! Also, it's from different cameras (M6 and RTS III) and they both expose perfectly...so it's not the camera(s) as far as I can tell, or my metering... I've got 20+ rolls I found I hadn't processed, so I'm doing two at a time trying to get them right before doing a bigger batch.
