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.

Neither do I. I keep having to scroll up and check that I'm still in the Photographic Science and Technology forum

I call it Photographical Obfuscation (PO). If the correct scientific or technical word, for example, is 'illuminance', go ahead and say 'brightness' instead - thereby confusing everyone, who will now respond according to what they think 'brightness' is . . .

Perhaps some of us should head to WikiPedia and learn the correct words?
