I'm hoping for a little help identifying the film pictured below. I'm sure it's worthless and I don't know how it was stored before I got it a few years ago before I froze it. All I can tell from the packaging is it's 400 ISO color neg film. So what the heck is this stuff? I'm just curious. Also, if it's indeed worthless then I'll use it to function-test a RFB I just bought.
