Light falloff refers to the decrease in intensity of light as it moves away from its source, following the inverse square law where intensity diminishes with the square of the distance. This principle is crucial in photography, cinematography, and computer graphics, affecting how light is modeled and perceived in various visual contexts.

Light Falloff

Decrease in intensity

The Inverse Square Law describes how a specified physical quantity or intensity is inversely proportional to the square of the distance from the source. This principle is fundamental in fields like physics and astronomy, explaining the behavior of phenomena such as gravity, light, and sound as they spread through space.
