Using Poser Pro 2010 one cannot parent a camera to anything. So I thought, well why not parent a light and use the shadow cam light to render the scene. So I tried this and everything blew into little tiny bits and pieces and Poser CRASHED! OK, I picked up the pieces and tried again and I see that with the Hierarchy Editor it's possible to drag a dolly camera onto a prop or character's head and that works just fine. Just don't give up.
