I think this is probably a bit of an odd question, but what the heck.
Back in the early part of the '90s, I took a bunch of road trips on which I took a bunch of photos of scenic places, many of which I think are pretty cool. While I know generally where these photos were taken (e.g., Medicine Bow National Forest and Acadia National Park), I'd love to know EXACTLY where they were taken. Note that these were all taken with a film camera, so there's no geo-tagging or anything like that.
Is there any sort of app or service where you can upload a scan and get location information? If not, someone with the technological wherewithal should make one.
