Don't worry. I was giving the point of view from the expensive dongle
Robin Myers alluded.
A bad capture can make a bad reproduction of a only 12 pigments
artifact. You can make better aproaching to the original the way you
introduce more knowledge and more technology.
The use of a ColorChecker SG (140 patches) will give a better
rendering than a ColorChecker Classic (24 patches).
And sure that I haven't to tell that there are other parameters for
image quality and the use of IT8.7/1 and IT8.7/2 targets for
photographic materials.
Sorry if I don't discover your curiosity. Maybe Mr. Robin Myers can
shed more light.
