Can you elaborate on what makes something creative or not?
On the 2nd point, the camera guides photographer. Watch anyone take a selfie, they use the camera to decide what to do with the camera. It is iterative.
Sure. It's like having a friend who can draw. You detail to them something you're picturing in your mind, and they make it into something actually real.
Who would have ownership over that art piece? Who actually did the work to make it exist?
Copyright doesn't protect ideas, it protects the specific creative expression of those ideas. By creating a prompt you're creating an idea, but that isn't a copyrightable, creative action. You're just the 'ideas guy' for a robot artist.
And again on the 2nd point, the camera doesn't guide the photographer. It can help them dial in their vision, but they're in full creative control at all times. It guides you no more than a hammer guides you to the nail.
