I've been looking everywhere, but I can't find the instructions for altering your view in Vanity Mode. Searching at uesp wiki didn't turn up anything, though I thought I saw something out there once.
What I really want to do is change the camera angle on my character sideways as I'm running around. I know you can zoom in and out by holding down Shift and rolling the scroller on the mouse, but I'm always looking at my character's backside.
I knew it could be done, because if you go out on youtube.com and look at all the Oblivion videos, lots of people are getting all sorts of good camera angles. Fun stuff.
