Cos'è luminanza?

Luminance is a measure of the brightness of a light source or surface, typically expressed in units of candela per square meter (cd/m^2). It is a physical quantity that quantifies the amount of light emitted or reflected by a surface.

Luminance is an important parameter in lighting design, as it affects how well objects can be seen and how colors are perceived. High luminance values result in brighter surfaces that appear more intense and vivid, while low luminance values result in darker surfaces that appear dull and less visible.

Luminance is related to luminous intensity, which is a measure of the amount of light emitted in a specific direction, and illuminance, which is a measure of the amount of light falling on a surface. Together, these parameters help describe the overall brightness and visibility of a light source or scene.
