Lighting Technique

Three point lighting

1. Key Light - Most brightest and dominant light of set up
2. Fill Light - Put opposite of the key light to fill in the shadow left in from the key light.
3. Back Light - makes an outline that separates the subject from the background

• for Noir to work the lights must have a strong key light and strong back light

This is a very useful picture that shows different lighting ways you can use to create a noir  look to my subject.
