calibrating your monitor affects both the hardware (the global effect you are seeing) and the software. You need both to get accurate colors. The hardware (calibration per se) part consists in configuring the graphics card's LUT to get a good approximation of colors. The second part is profiling your screen and the result is used by color-managed software. If I understood correctly, the profile tells the software both how to render each color and which color cannot be rendered (used to know which pixel is out of gamut on screen). If you use dispcal (https://displaycal.net/), then both steps are explicitly shown in the UI. What's both nice and confusing is that both informations are stored in the same file (.icc). -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
