What is the boundary between "deepfake" and "photoshop" (i.e. regular human "fake" or edit?)

I suspect it's going to become popular for both consensual-deepfake of oneself (PR, magazines, actors, pop stars, any form of public speaker) and "bought out" deepfake (actors selling out their image rights and then losing creative control; dead actors, etc.)

The political-deepfake is really going to accelerate the debate over how much free speech permits you to just lie about people, though.
