If you change the brightness, the best thing to do is rerun the preview
scan. It's not horribly slow. Otherwise you're not seeing the result of
the longer integration time. I imagine Ed could code Vuescan to estimate
the change produced by the brightness control, but people would probably
complain that it wasn't accurate. Changing the brightness (equivalent to
analog gain) and redoing the preview scan is really the only way to be sure.
