Fresnel

Definition

A Fresnel is a type of lighting fixture that uses a special lens to focus light in a way that creates soft, diffused illumination, commonly used in film and theater production. This design allows for greater control of light intensity and spread while minimizing the bulk of traditional lighting equipment. Fresnels are essential in crafting specific moods and atmospheres in complex scenes by manipulating shadows and highlights.
