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
It's true that 1990s pirated videos where someone snuck a handheld camera into the cinema were often very low quality.
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.
That's a freaking massive LED wall... with professional cinematography on top. If you believed my comment was intended to imply that I believed that's somehow impossible, well... you and I have a very different understanding of what it means to "just take a picture of a high-resolution display"...
