absolutely fantastic. nice polish and functionality. i would pay a shareware fee, but for now, will donate $10.00 to continued development.

my new 24" imac was burning my eyes out until i found this great app. my new 24" imac is so ridiculously bright, and the normal brightness control in display system prefs only dims the display to what i would call a normal brightness. it was unbearable working at night with the room lights dimmed.

btw, thanks to the reviewers about screen calibration. i will check into this, although, after turning on shades my calibration looks perfect to my naked eye.
