luminance
Luminance refers to a precise, measurable physical property of light, distinguishing it from brightness, which is a subjective psychological perception. It is primarily used in technical fields such as optics, photography, and display engineering to describe the actual amount of light emitted from a surface regardless of the observer's visual sensitivity.
Because it is a scientific measurement of intensity per unit area, the term carries a clinical and objective connotation. It is rarely used in casual conversation, appearing instead in specifications for monitors, lighting standards, and image processing algorithms.
Meanings
Examples
We must calibrate the luminance for the presentation.
The detective noted the low luminance of the room.
