Hi
Short version:
Which settings if any should I adjust manually on my Eizo CG243W (and Macbook Retina) prior to calibration/profiling with a Spyder3 Elite and ColorEyes Pro (or Color Navigator, or dispcalGUI, for that sake)?
Background:
I have earlier calibrated/profiled my Eizo CG243W with very satisfying results. I believed the manual adjustment was just in the lack of a puck+software. On my Eizo, I have covered the physical controls with tape so as not to hit them inadvertently. The MacBook has no physical controls to adjust anything else than brightness, but the Mac OS has a software tool for what it calls 'calibration'. Is this the equivalent of physical controls on other monitors? BTW, my Samsung Sync Master193P has none.
Now, trying to read up on monitor calibration , I am confused by these passages in the documentation of dispcalGUI:
1-"To meet the user-defined target characteristics, it is generally advisable to get as far as possible by using the monitor controls, and only thereafter by manipulating the output of the video card via calibration curves, which are loaded into the video card gamma table, to get the best results."
2-"Colorimeters need a correction in hardware or software to obtain correct measurements from different types of displays [...]
You need a spectrometer in the first place to do the necessary measurements to create such a correction, or you may query dispcalGUI's Colorimeter Corrections Database, and there's also a list of contributed colorimeter correction files on the Argyll CMS website [...]
Starting with dispcalGUI 0.6.8, you can also import generic corrections from some profiling softwares by choosing the corresponding item in the “Tools” menu."
Well I don't have a spectrometer, and there is no such correction file on the CD that came with my Spyder3 Elite, nor can I find one on the Datacolor web site. Neither the ColorEyes nor the Eizo Color Navigator software have ever asked for such a correction file (as I recall it). And as said, I have made rather good profiles for that Eizo. - And there is no file for the Retina nor for the Eizo CG243W on the places given in the dispCalGUI text.
Ptarmigan,
http://www.l-camera-forum.com/leica-forum/digital-post-processing-forum/116801-colour-calibrating-eizo-cg243w-coloreyes-display.htmlwho had the same considerations, thinks he has figured out that it is the Gain controls of R,G and B that should be adjusted. But as I understand it, that is the white balance. To what target should that be pre-adjusted? Setting all to 100% would be the native White Point of the screen (-?) which I will use for one or some profiles, but not for others.
What am I missing? Do I have to buy a spectrometer? Color trueness is important to me, but my need is for landscape photography, not art reproduction.
Thank you for your advice!
