I'm facing one tricky problem here. Am on a room, with only a single window open. The light that comes into my Macbook Pro is the ambient light from that window, facing the lid of the notebook ( 13" mbp ), so, that the only light that comes into it, is indirect light reflected by a white wall. I do this, because I am not into turning up the ceiling d65 lights during the day, I'd rather re-calibrate ahead of any work.
Anyway, am giving this MBP it's first calibration, and the Spyder 3Pro asks me to tune the desired brightness of the LED display. And I never manage to get it into the desired target. It's either halfway down, or halfway up, depending on the brightness level I set. I'm using the ambient light compensation, and seems like I would need to set the brightness up or down by 1/2 point in the F1/F2 settings.
Maybe this is a really silly question, but is there a way to fine tune the backlight brightness on a MacBook Pro other than using the lighting setting keys on the keyboard? And RGB settings? This isn't my first mac, never managed to find these controls myself.
