Photoshop would probably be easier if you have it (or are willing to pay for it), but I think it may also be possible to do with tools like Krita and some of the generative AI plugins people have made for it – e.g. https://github.com/Acly/krita-ai-diffusion
I haven’t messed with it personally, but it’s on my list of fun looking AI things to try out eventually if/when I finally get a better GPU.
This story may be amusing, but it’s actually a serious issue if Apple is doing this and people are not aware of it because cellphone imagery is used in things like court cases. Relative positions of people in a scene really fucking matter in those kinds of situations. Someone’s photo of a crime could be dismissed or discredited using this exact news story as an example – or worse, someone could be wrongly convicted because the composite produced a misleading representation of the scene.
