I have some pictures from 2019 that I took on a disposable camera that are starting to collect these strange pinkish-dots all over them. The photos: https://imgur.com/a/WGY9TY4 For some context, these photos were pristine up until a few months ago. These photos have been stored on the wall in a room that gets a half decent amount of sunlight but the photos aren’t facing towards the windows at all. What could be happening and how can I prevent these photos from further degradation?
Looks moisture to me. Like there were hit with drops of liquid.
Bad chemistry would have the prints fade evenly. Not in little spots like that.
