Low Budget Lighting Part 1.
3-Point Lighting Set Up
The standard film lighting setup consists of three elements: the key light, the fill light, and the backlight:
Key light- Main lighting source
Fill light- Handles shadows
Backlight- Separates subject from the background
Key Light
The key light is the main light and first light you set. It is the strongest light and usually comes from a high angle and from the side.
Fill Light
The fill light is either a weaker light or a reflector. It fills in the shadow for the key light.
Backlight
The backlight serves to create an edge light that separates your subject from the background.
The following diagram illustrates the principle.
