WebDec 8, 2014 · Luminance is a measure of the intensity of light that reaches the eye. Its unit of measure is candela per square meter (cd/m2), which you don’t really need to know. What’s important is it’s an absolute measure of the intensity of light. Brightness and Value are the same thing. They’re the perception of an object’s luminance. Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture (see YUV color model), separately from the accompanying luma signal (or Y' for short).
