Lighting is an important technical element in film and media that helps convey genre and mood to viewers. Different lighting setups, such as low-key lighting for suspense and high-key lighting for comedy, elicit different emotional responses from audiences. A director can use mixtures of lighting within a single scene to portray changing moods and feelings over time. In film production, the use of lighting is crucial to engaging audiences and achieving profitability by effectively setting the genre and tone.
