An 8:1 ratio in cinematography refers to the difference in intensity between the key light and the fill light, indicating that the key light is eight times brighter than the fill light. This significant disparity creates a noticeable contrast that affects the overall mood and texture of the image. Such a high ratio enhances dramatic effects, contributing to visual storytelling by emphasizing shapes and shadows, thus influencing the viewer's emotional response.
