I’m not talking strictly about ideas, I’m talking about a human having a vision, and taking action to make that vision into something. Whether something is copyrightable requires a “human element,” which is the reasoning behind why machine or animal generated content cannot be copyrighted, because they lack that.

So the question is if someone tweaking an image, even if they’re merely selecting things, then is that a sufficient human element to say that a person had enough hand in creating it?
