How do you ascertain that the finished hw calibration is set to '70%'? I hardware calibrated my Unibody 15" MBPs andas well as my 2 newly arrived 17" Unibody MBPs (one gloss, one 'anti-glare'), with an Gretag MacBeth Eye-One Pro system, a ColorMunki Photo unit, and the Spyder 3 Elite, usually running the Eye-One Pro profile for most runs. My clients output on everything from Epson 3800s to Heidelbergs, ProPhoto RGB to Hex to 7+ plate runs, spot/lacquer/process, newsprint to 10-point coated... my 15"Unibody MBPs (glossy, natch) can
just attain acceptably accurate calibration to IS, period, and I'm wondering if, between the narrow viewing angle and the apparent dithering in some color midtones, whether the 15" MBP displays are hardware 24-bit, but rather 16-bit dithered... my 15 MBPs are barely acceptable for the critical photo retouching and pre-press design work I do every day in Quark, P-shop, Illustrator and various Binuscan, etc. apps... OTOH,
both the gloss and anti-glare 17" MBP displays, once calibrated, are of course both warmer and dimmer than the Apple factory LCD profile and the setting of '100%' brightness in System Preferences>Display. NO quality calibration hardware CMS profiler result will NOT dim any display in good condition (this obviously doesn't include 2-3 year old non-LED backlit laptop or desktop LCDs, even IPS ones), and usually warm ANY display, whether LCD or CRT... back in the day, just north of 5K color temperature was more common than the 6.5k now often in use. The mechanical brightness capability of a laptop display is more relevant 'back in the day', when the red guns in particular of the Barco and Sony CRTs 'dimmed' with age; they needed to be MUCH brighter than what was needed for pre-press calibration, to compensate for the CRT's phosphor 'decay'/RGB gun aging...
all
that said, (sorry about the lecture), I'd be very interested in how, on the 2009 17" MBP, you were able to ascertain that your display after hardware calibration was at '70%' brightness... I set the display to 100%, turn off the ambient sensor, of course, and then do the calibration... the screen's dimmer when that profile is selected, but in ALL cases, with ALL my hardware profiles, the screen remains, at least in System Preferences, at 100%... is there a place in the s/w of your calibration unit that tells you what it 'dimmed your display to, using the System Preferences' '100%' Brightness as the baseline?
Thanks in advance! =^D
