(*) To be altered, a pixel has to be 1) in the active layer and 2) covered by the selection mask, if there is one.
Thank you for your reply. I'm not sure if my solution corresponds to your first answer, but you did point me in the right direction, and I now understand the principal explained after your asterisk. 'Select>None' WAS grayed out, but I clicked 'Select>All'. When I did that, "Select>None" was no longer grayed out (logically), and now I can adjust the brightness/contrast of both layers.
