Relative luminance: Measurement, Relative luminance and "gamma encoded" colorspaces & Relative luminance and perceptual spaces

Relative luminance Y {\displaystyle Y} follows the photometric definition of luminance L {\displaystyle L} including spectral weighting for human vision, but while luminance L {\displaystyle L} is a measure of light in units such as c d / m 2 {\displaystyle cd/m^{2}} , relative luminance Y {\displaystyle Y} values are normalized as 0.0 to 1.0 (or 1 to…
