@f4grx @daniel @gloriouscow this, plus edge-detect and simple HSL-to-layers representation can be super helpful at detecting photoshopped stuff. compare the shopped image with its "saturation" layer - you could see how things were pasted, some brushes were applied on top in layers, some copy-pasting was done, too. https://tech.lgbt/@NanoRaptor@bitbang.social/115206029097865834

It's not bullet-proof, of course, and if it's a photograph, then modern weird compression and "smart" filters on the phone cameras can create some funny-looking artifacts. They'll likely be all of the same quality, though. Reference two - https://tech.lgbt/@nina_kali_nina/115792788459542758
