Relative Brightness:


The relative brightness refers to the measure of the intensity of light emitted from a light source or reflected by an object, with respect to a standard reference.


Relative brightness is a comparative measure that provides insight into how bright an object or light source appears compared to a known standard. It is usually expressed as a ratio or a percentage, indicating the relative luminosity or brightness of the object in question.


Relative brightness is commonly used in various fields, such as photography, vision science, and display technologies. In photography, for example, relative brightness helps in determining the appropriate exposure settings to capture a well-balanced image. In vision science, it contributes to understanding the perception of brightness and the workings of the human visual system. In display technologies, it aids in designing and evaluating the luminance properties of screens or displays for optimal viewing experiences.
