Had a guy bring in a camera he said was haunted...
This was about two years ago at my old shop in Austin. He was dead serious, said the shutter fired on its own at exactly 3:33 AM for three nights straight. He'd even marked the lens cap with tape to prove it moved. I opened it up and found a single, tiny metal shaving from the manufacturing process that was bridging a circuit when the temperature dropped at night. Charged him $75 for the clean-out. Ever had a customer give you a repair reason you just couldn't make up?
Seriously, a haunted camera? That's just a mechanical glitch with a spooky story attached. People love to jump to the supernatural before checking the simple stuff. Glad you found the real fix.
Remember my friend's old Polaroid? It kept spitting out blank photos with these weird, dark smudges. Turns out the film was just expired and the rollers were dirty.
That "haunted camera" thing is wild. My buddy had a similar story with an old radio that would turn on by itself. Just a loose wire in the plug making a bad connection.
