What term describes the difference between the brightest and darkest areas of a video frame?

• A. Brightness
• B. Contrast
• C. Saturation
• D. Gamma

Answer: (B)

Contrast describes the difference between the brightest and darkest areas of a video frame. This range shapes how clearly light and shadow define objects, textures, and depth in an image. A scene can be bright overall but have low contrast if the lights and darks aren’t very different, or it can have high contrast with strong highlights and deep shadows that make details pop. Brightness is the overall light level of the image, not how spread out the light values are. Saturation is about how vivid the colors are, independent of light and dark. Gamma is the nonlinear way that input luminance maps to output brightness, which changes how midtones look and can alter perceived contrast without changing the actual light range.
