It can also be referred to as “saturation”. C=80 M=10 Y=45 K=0 To clarify the difference, illuminance refers to intensity of light falling onto a surface, while brightness refers to the visual perceptions and physiological sensations of light. PROCESS 0.000000 La luminance est une grandeur correspondant à la sensation visuelle de luminosité d'une surface. 100.000000 The geometry of the situation results in the interesting fact that the observed surface brightness is independent of the distance of the observer from the extended source.
