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?
The pink dots are probably from improper washing from the photo developer. It takes a while for the results to show up. If it was from exposure to sunlight, the color fade would be more consistent across the whole print.
