What is Fill Light?

In photography and cinematography, fill light is a term referring to a type of artificial light used to fill in the dark areas of a scene. It is often used in conjunction with other lighting techniques such as backlighting and key lighting. Fill light can be created using various methods, including spotlights, floods, panels, and reflectors.

The most common method is to use an on-camera flash unit pointed at the subject from the camera’s position. This is often referred to as “bounce flash” because the flash unit is usually directed into a nearby wall or ceiling, which then reflects the light back onto the subject. Another popular method for creating fill light is to use off-camera flash units placed around the perimeter of the scene.

This technique is often used in fashion photography and can produce very striking results. Fill light is an important tool for photographers and filmmakers alike because it helps create more balanced and flattering images. Without fill light, scenes can appear flat and one-dimensional.

But when used correctly, fill light can add depth and dimensionality to an image while still maintaining a natural look.
