It might be cool if there was some way to 'link' photos taken with the Exposure mod to different locations on the map to give yourself a set of reference landmarks for navigation. (this would pair especially well with a 'hardcore navigation mode' or something that disabled the player marker, requiring you to actually figure out where you are on the map manually.)

Ideally this would be directly integrated into the Atlas itself, but that might not be technically feasible depending on how differently both mods work internally, so it might be more practical to literally have some link system where you can assign a photo to a location and then that places a marker on the map which, when clicked, will highlight, jump to, or otherwise identify the picture in a photo album
