hoestly that's an real disservice to how hard it would be even to paint something from a projected image, this is the same kind of reductive judgement digital artists get today about making their art, I'd challenge anyone to try and take a camera obscura make a painting that looks as good as that one without the vast experience and training behind even simple things like handling and mixing pigments and filling in details that have moved.

even just knowing what you're looking at is a process of un-training your brain, a good art education actually starts from learning to see "correctly" and unsee all the shortcuts that your brain takes.
