I just ran shot and processed two rather old rolls of HIE - they were at least eight years old if not older. The one roll had been refrigerated/near-frozen the entire time. The other was shot back in 2004, put aside and forgotten until today. Both had a very obvious level of base fog. What's the best way to deal with this on subsequent rolls (I have six left)? Would benzotriazole work, if I'm souping in Pyrocat HD? Any other thoughts? All input and feedback is much appreciated.
