Or, happy accidents.
I had trouble loading a roll of Ilford HP5 into my Pentax K1000 just about this time last year. I loaded and reloaded and remember reloading it again. I wasn’t sure the film was advancing correctly while I was shooting, and eventually I just stopped shooting, rewound the film and took it out.
And then I forgot about it for months, until I handed it to my son to develop at school. I was right… it hadn’t advanced correctly at all. I forgot about the negatives until I was clearing out a bit of junk in my office a few days ago and almost threw out the film canister that contained the negatives.
I’m still working on figuring out the best settings for my scanner, but I think the resulting accidental double, triple, and maybe more exposures are at least interesting.
