What if Louis XVI ask Antoine Callet to use a lighter color for his skin? Does he own the Callet painting copyright?

You can prompt whatever you want but won’t own the copyright. Photographer will choose himself if he follow or not your "prompt", what side and angle he tilt, the zoom, when to press the shutter…

What if I set a delay but it is not technically me who presses the key? Would that count because it was me who set the delay? What if I tell a friend to set the delay?

All this is pretty much grey area anyways. Both sides have merit.

To me, it just shows how bogus the whole idea of copyright is.

I would not say bogus, I would just say it's a bit too easy to get copyright on a photograph.

But it would be difficult to adjust that without making the rules even messier.

Agreed.
