A gray target would be nice but I don't think I could afford the import at
the moment. Media settings probably do affect OD range as they would be
curve transforms of some sort based on the film response curve. They
shouldn't affect the raw scans; as far as I know, only the brightness
setting affects the raw scan by changing the integration time.
