I've got a spare lens protector/uv filter lying around that I don't need so I was wondering if you guys knew something cool I could do with it?
I'm not really talking about just smearing vaseline on it or something, if I want some kind of instagram filter I'll just do that on the computer. I made a solar filter (to look at sunspots with) out of another lens protector with some of that film that those eclipse viewing glasses are made of that I bought off amazon, cut it out and inserted it into the filter. I'm looking to do something similar, something cool like that.
TL;DR: give me ideas for something cool to do with an otherwise useless lens protector
