After reading a post on Reddit where someone wanted to find files that weren't a certain aspect ratio, I was curious as to what could be done with Exiftool. A quick google brought up some code and I was able to make a config file out of it. It finds the lowest common denominator and uses that to get the lowest integer ratio. No decimals involved, so if you want to find something like 2.35:1, you'll have to figure something else out.
Sample output

Interesting math. Looks like fun. Don't tell me why it works... I want to figure it out myself when I get a chance. :)

I have no idea how it works, but it's apparently Euclid's algorithm (https://en.wikipedia.org/wiki/Euclidean_algorithm). As usual, I just copied the code from elsewhere.
