A composition viewfinder I made using thread and a slide mount
I got a big bag of slide mounts from a garage sale a few years ago. I’ve been struggling what to do with them, since I don’t shoot film (the price of film these days, sheesh); but I had an idea to turn them into a pocket/keychain size viewfinder that I could easily remake if it broke.
The thread is spaced exactly on the thirds, using a ruler with 1/64th inch ticks.
I used a slide mount, red thread, and superglue; as well as parchment paper to keep it from sticking to my desk and fingers.
