This is the amount of light you’ll be “contrasting” against other sources, such as your fill light or background light. What Are Contrast Ratios? A contrast ratio is a representation of the difference in exposure between two areas in a frame. On set, you typically measure this ratio in stops, but you can also measure all contrast ratios IRE. In theory, you can compare any two areas in the frame, but the majority of the time you will be working with either a “Key to Fill” ratio or “Key to Background.” A clean print at a typical movie theater may have a contrast ratio of 500:1, a transmissive digital projector is around 200:1, and a reflective digital projector (i.e. DLP) is around 500:1 under nearly ideal circumstances. To recap, contrast ratio is the difference in the bright and dark areas of a scene cast from the key light compared to the fill light. To measure this ratio one will use a light meter and the ratio will be calculated in F-stops. Each stop moving up or down the range will create a doubling or halving of light.
