Another arm in the arms race. The next gen of face generation will have this mastered.
Does it really work like that? I would say that they are not trying to fool any test, just getting harder to be detected. The goal being looking completely realistic.
This is one of the basic techniques to spot AI fakes:
The "test" they're trying to fool, is kind of the Turing test: whether humans can tell them apart.
Consistent illumination and shadows is a rabbit hole we really don't want to hop into.
Outside of very obvious anomalies even a trained eye will have a hard time discerning what's going on.
Some are very easy to spot, like a shadow of a character, that's missing a limb on the shadow, or has different placement or pose. Illumination or parallel surfaces where they vary in shadowing without a reason, is also a dead giveaway. But the mist damning evidence is having one scene, then a slightly different scene in a reflection.
There are reasons for human authors to do any of these on purpose, but unless that purpose is part of the work, they're most likely AI mistakes.
Of course it's kind of funny how there is already a large overlap between the best AI art, and the most senseless "modern art".
