Today in Class I learned about 3 Point Lighting. If you want to light your subject proportionately you need 3 lights. Your Key light, Fill light, and Back light. For more information on lighting here are some links that can explain it better than I can. :)

First, you need your Key Light.
Second, you need your Fill Light.
Finally, you need your Backlight and then you have a beautiful lit subject for your photo!! :)
Have a great day!
