Everything about Luminance

Photometric measure

Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted from, or is reflected from a particular area, and falls within a given solid angle. Wikipedia →

📖 Definitions

Noun The quality of being luminous.

Noun The amount of light that passes through, is emitted, or is reflected from a particular area, and falls within a given solid angle.

Noun The luminous flux emitted in a given direction divided by the product of the projected area of the source element perpendicular to the direction and the solid angle containing that direction (i.e. luminous intensity divided by unit area), measured in stilbs or apostilbs.
