Three Point Lighting

- The three point lighting technique is a standard method used in visual media such as video, film, still photography and computer-generated imagery.
- The goal of three point lighting is to create the illusion of a three-dimensional subject in a two-dimensional image.
- There are three lights used in three point lighting, which are the key light, the fill light and the back light.

The Key Light 

- The key light is the main light used on the subject. 

- Whichever way the subject is facing in the frame, the key light should be on that side of the camera. 

The Fill Light

- The purpose of this light is to fill in the shadows created by the key light, preventing them from getting too dark. 

- The fill light shines on the subject from a side angle relative to the key light and is often placed at a lower position than the key light. 

- The fill light should not create a second shadow. If two shadows can be seen then the fill light is too powerful and needs to be reduced. 

The Back Light

- This is used to separate the subject from the background. 

- The back light shines on the object from behind, often to one side or the other.
