I know that the courtiers of Versailles have been doing this for ages and that adjusting your camera angle isn't a new idea but I quite liked this post by Pamela Galli.
You should also check out the free HUD to adjust your camera angle from Penny Patton. A link for that is also included in Pamela's post: Cut Mesh Prims by Changing Your Camera Angle!
Happy Angling
