The raw data are brightness values for the array of pixels.

Brightness is human perception. Measurements are not. Arrays of pixels on the sensor do not have brightness because they do not emit or even reflect light. I do not see how loose definitions and terms help.

Such is Photographic Science

PS. PO.
