I recently processed a roll of fuji 800 for my roommate that had been sitting in a plastic disposable for around 10+ years (on top of the microwave at that). Well knowing that c-41 film is really silver based I knew that I could just develop with a b+w dev and be relatively alright. Well negs came out with images and exposure looks fine. But there's one problem though... I can barely see through them. Held up to the light I can see the images fine and flipped to emulsion side I can see the images. But they're beyond bulletproof. I'm just trying to make some simple contacts and get on with life but as of now I'm up to around 64 secs, wide open at f4, 8x10 coverage, with magenta maxed out, and finally getting something with mgiv rc. My question is what is this? Some kind of orange mask on steroids? Or is it a result of my voluntarily haphazard development time of 15 minutes? The emulsion side looks developed totally fine. It's the base side that is through the roof in darkness. I knew the negs would take work - I just didn't think they'd be this insane.
