I recently developed a few rolls of hp5 for a personal project I was doing. I developed them like normal, and i'm pretty sure my exposures were fine (never had an issue with that before) but the negatives turned out VERY thin. I figured it was a chemical issue, so I replaced the developer and it was fine (a friend succesfully developed with it like normal). I tried it again with another roll and again, the negatives were quite thin. When I looked at the film leader that is usually pitch black from exposing it when loading the film, I saw that it wasn't black. It's almost as if the film was faded or somehow prevented from being exposed. or something. That clue told me that the issue wasn't the camera or my exposure settings most likely. what might be the issue? the film was kinda old, maybe 2 years at the most, but I'm not sure even if that would have done it. it might have been some film i kept in my photo backpack for a while, and even through a few x-rays. any suggestions? I just shot another roll with it (with brand new hp5) and i'm hesitant to develop it until I know what the problem is.
