Luminance is the luminous intensity per unit area projected in a given direction. The SI unit of luminance is candela per square meter, which is still sometimes called a nit. Luminous intensity is the luminous flux per solid angle emitted or reflected from a point. WebSure, let's break down the formula step by step. L = F x 4πd^2. This formula is used to calculate the luminosity (L) of an object based on its flux (F) and distance (d). The luminosity is a measure of the total amount of energy emitted by an object per unit time. The flux is a measure of the amount of energy emitted by the object per unit area ... ce reeve
