Glossary Of Photography Terms [1]

Luminosity Mask A luminosity mask is a sophisticated selection tool used in digital image editing software, such as Adobe Photoshop, to create precise selections based on the brightness values (luminance) of an image. Luminosity masks allow photographers and digital artists to target specific tonal ranges or brightness levels within an image, enabling selective adjustments and enhancements while preserving detail and avoiding overprocessing.

Luminosity masks are generated from the luminance values of the image, with brighter areas generating lighter masks and darker areas generating darker masks. By combining and refining luminosity masks using blending modes, layer masks, and adjustment layers, users can control the distribution of tones, contrast, and exposure in their images with unparalleled precision and flexibility. Luminosity masks are widely used in advanced image editing workflows, including exposure blending, luminance adjustments, and selective retouching, where precise control over tonal values and image luminance is essential for achieving professional-quality results.
