Title: Can I make a profile of new monitor BEFORE actually calibrating and profiling it
Post by: Ellis Vener on June 19, 2018, 06:11:53 pm
In case my headline is not clear enough: I have a new display and before I actually calibrate and profile it, I'd like to generate an .icc profile as a native baseline for comparison purposes using ColorThink software.

Any ideas?

Can I assume you wish to use an instrument? If so, I can't think of any software off hand that will do this but it's certainly possible. Most of the products I can think of will ask for some calibration aim point first which you wish to avoid. Doesn't mean none exist. You could use the built in Apple Calibrator and not alter anything and it will create a profile but the value of that profile is iffy at best and of course, no instruments. You can measure the display prior to the first calibration with a number of products but I don't know any that will then create a profile. Begging the question, why do you need a profile, can you just start with measurements of white point, cd/m^2 etc? BableColor CT&A should allow you to measure that display but not produce a profile.
You may wish to ask on the Apple ColorSync list. Again, it is possible there's some software that will bypass any calibration and produce a profile of the 'native' state but I know of none.

I think it may be possible to do this with Displaycal

Well, depending on the display and your hardware/software you should be able to simply profile your display with native white point and native gamma and depending on your display, set the color space like sRGB or Adobe RGB.

If that doesn't work you can create patches of 100 red, green and blue as well as white and measure those patches (depending on your spectra or colorimeter) and in Photoshop under Color Settings>RGB>Custom RGB enter in the measured colors. For gamma, I would assume gamma 2.2 or 2.3 (not sure how to measure gamma) then save that our as an RGB profile.

Gamma and actual cd/m2 still a guess however.

Does the display not have a default profile that it came with?   

:Niranjan.

Far more important, does it actually reflect the condition of the display?

Probably not.  My Dell came with a default profile.  When I did calibration/profiling with ColorMunki, the difference was night and day.

Well of course ArgyllCMS/DisplayCAL will do this, because calibration and profiling are separate steps, so you can skip the calibration step and just profile as-is.
