As long as they're not GenAI altered photos, I'm cool with these things.

I'm a pretty avid member of various history groups, and one thing that has absolutely driven me nuts for the past couple of years is how many people there are that use AI for upscaling and colorization of photos - not knowing or noticing how the models fundamentally alter the photos. A couple of zooms in on the photo, and it is nightmare fuel.

A week ago me and some members spent a couple of hours trying to find a building from the early 1900s, because someone had uploaded a photo and asked about the building. Sifted through old maps, newspapers, etc. but couldn't find anything. Turns out said photo had been upscaled via AI, which in turn had added some buildings here and there.

But, yeah, for stuff like OP posted it could work out nicely.

Likewise. There’s this older woman who is trying to add some historical color to our local beach town FB group by using some terrible AI tool to colorize pictures from the early 1900s. She doesn’t accept any feedback that it’s problematic to share what are essentially fake pics in that way.. they often just randomly remove people, or add new ones. Buildings are changed, cars are remodeled, it’s crazy how different the before/after are. The comments are usually split as well, but I absolutely loathe how AI is used there. She means well, but the tools are so bad for this and so poorly explained.

Do you have any recommendations for colorization tools? I agree that all of the popular image models subtly tweak faces, it is very uncanny when working with pictures of people I knew before they passed. In a pre-GPT age, there were some good but not great colorization tools, and as far as I can tell you can’t get better-than-2020 performance unless you’re willing to get your expression adjusted or your eyebrows redone.
