3. The useable exposure range of a sensor - or the range of subject brightness is called what?
On a scanner; it guesses what the pixels look like in between the ones the scanner can actually measure.
Luminance is light reflected from the subject (measured by a reflected-light meter) - while Illuminance is light falling on a subject (as measured with an incident light meter)

6. What does the term "stop" mean?
A change in illumination
Cyan
Click with the neutral-point dropper on the selected color
four times more
7. An in-camera reflected meter reading a very light toned scene indicates an exposure of 1/250th at f/8. For a correct exposure - what should you do?
Use positive exposure compensation (overexposure). A reflected meter reading will attempt to make the scene 18% gray - employ overexposure to adjust.
