Lighting!

Have you ever wondered if you could have a cheat sheet of various lighting setup that shows the subject would show up?
Someone has attempted to do just that here: http://www.wimp.com/facechanges/

Hmmm the only problem seems to be the fact that they have not called out where they had positioned the lights. So here is what photographer Pat David had done using an open source 3D modeling software called Blender 3D: http://blog.patdavid.net/2012/03/visualize-photography-lighting-setups.html
Neat!
