I am not sure how verifying that a photo was unaltered after capture from a camera if very useful though. You could just take a photo of a high-resolution display when an edited photo on it
But did you know large portions of The Mandalorian were produced with the actors acting in front of an enormous, high-resolution LED screen [1] instead of building a set, or using greenscreen?
It turns out pointing a camera at a screen can actually be pretty realistic, if you know what you're doing.
And I suspect the pr agencies interested in flooding the internet with images of Politician A kicking a puppy and Politician B rescuing flood victims do, in fact, know what they're doing.
