Kate has claimed responsibility for making the alterations to the photos. The originals will not be released and nothing is known about when they were taken.
Well, she allegedly claimed responsibility, someone could have impersonated her. The royals don’t actually write their own social media posts or public updates, what’s posted is discussed and agreed by a bunch of public relations people, and posted by a relevant team on a relevant account.
Also, there are voices on like that say it’s a lie that the photo has just been edited. It’s actually been AI generated. If you review the issues pointed out by internet users you’ll see that this is not something mere photoshop editing would do. Have a look at the hands in particular, AI is known to mess up the hands the most. As someone who uses image processing software and AI image generators at work I haven’t been reassured by that post. I’m a very intermediate user, not an expert though. There may be tools that I don’t know of that would lead to that result when processing an actual image, so take it FWIW. But I continue to be suspicious
