Webof photometric and radiometric units, detailed respectively in sections 7 and 5, with considerations on photon−number−based units in section 6. Section 7.1explains how, in general, photometric units are derived from radiometric units. Sections to 7.5 deal with the particular geometric conditions for the specific 7.2 photometric units. WebIn photometric quantities every wavelength is weighted according to how sensitive the human eye is to it, while radiometric quantities use unweighted absolute power. For example, the eye responds much more strongly to green light than to red, so a green source will have greater luminous flux than a red source with the same radiant flux would.
