Understanding how light works will allow you to more easily control it visually. Lighting expert Christopher Grey takes us through the inverse-square law and how it relates to lighting fall-off for portraiture.
To illustrate this principle, Chris uses one light, a softbox, and places it at different distances from his subject. He meters for the lit side of the face and lets the shadows fall. You can see the depth of light change as he moves the light closer and closer. He then builds a portrait setup, using fall-off to create a dynamic effect.
