Thrift stores are a gold mine of glorious potential. I have found luxury leather bags, exquisite vintage coats, jewelry, and my fair share of amazing/weird things.
I mostly trawl mine these days for forgotten cameras and film. Many people donate film to thrift stores- much of it expired- and for a fraction of the cost I’ll shoot it.
As you can see, most expired film gets grainy and can’t handle dark light at all. Colors are a bit off, too. However, when I found 4 rolls of Kodak Gold 400 speed film for $2.00 I definitely went for it. When I got the developed roll back from the shop, though, I found I only had about 12 usable frames- mostly because I had tried taking photographs at night, which on this expired film was nearly impossible.
Note to self with my remaining rolls: Be generous with daylight.
