luminances
Measured surface brightnesses
Luminances is the plural of luminance, the measure of light intensity emitted or reflected from a surface in a given direction.
The term appears in technical contexts—photography, display technology, vision science: The luminances of the two screens were calibrated to match.
In casual use, luminance often just means brightness, though technically they differ.
