Intensity can also be considered as the brightness or dullness of a color. CMYK This also means that increasing intensity can be viewed as brightening the image (while decreasing intensity can be viewed as darkening the image). 80.000000 100.000000 0.000000 1 brightness Power carried by a light wave: intensity and brightness. 4.998803 Usually the term bright is thought of as referring to something being light in value in addition to having a high level of intensity.

This tool can be either manual or automatic. 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.
