Description: Luminance is a measure of brightness in images that refers to the amount of light emitted or reflected by a surface in a visual space. In the context of computer graphics and graphic design, luminance is fundamental for the accurate representation of colors and visual perception. It is used to define how colors are perceived on different devices, such as screens and projectors, and is especially relevant in graphic design applications where color management and visual quality are priorities. Luminance is measured in candelas per square meter (cd/m²) and is closely related to human perception of brightness. In color representation systems like RGB and CMYK, luminance plays a crucial role in creating images that are visually appealing and true to reality. In graphic development environments like OpenGL and Vulkan, luminance is considered when rendering scenes and applying visual effects, ensuring that visual elements are presented coherently and effectively. Additionally, in the field of computer vision, luminance is a key factor in image processing and visual data interpretation, allowing machines to understand and analyze the visual environment more accurately.
