One thing that Kip says that I have to take exception with. He suggests using your lenses wide open (widest F-stop). I`d suggest stopping down your lenses about 2 or 3 stops. This is because unless you have very good optical quality in your lenses, you will have a lot of aberations towards the outer edges of the lens. By stopping down a little bit you avoid those areas of the lens and generally get higher quality pictures. Just remember that because you stopped down you`ll need slightly longer exposure times.
