Intensity

Definition

Intensity in lighting design refers to the brightness or strength of light emitted from a source. This concept is crucial because it affects visibility, mood, and the overall aesthetic of a set. Different intensities can create varying atmospheres, highlight specific areas, and influence how colors are perceived on stage or in film.
