Which light source is typically the brightest in a scene?

The key light is typically the brightest light source in a scene because it serves as the primary illumination for the subject. Its main function is to create depth, dimension, and shape, highlighting the features of the subject effectively. The key light establishes the overall mood and tone of the scene, making it essential for visual storytelling.

In contrast, fill light is used to soften shadows created by the key light, making it less intense. Backlight provides separation and depth by lighting the subject from behind, while accent light is used to highlight specific areas or details within the scene, contributing to visual interest rather than acting as the main source of illumination. The dominance of the key light ensures it plays a critical role in how viewers perceive the visual elements of the film.
