Good to know, GD. I thought of that, but didn't look it up. Controlling LED backlighting must be easier. Though you'd think it would be much brighter at 100%.
I re-read the manual for Dark Adapted today as I upgraded to the latest version. In it they recommend you do your monitor calibration with it turned off completely. Their reason is that once calibrated at full brightness, Apple's firmware or software will maintain the color balance and gamma down to the minimum in-computer brightness, and Dark Adapted will maintain and/or adjust it further as you lower the brightness with their add-on software adjustments.
