Hey @luxapy
To create a DCP profile you need:
- a
.ciereference file which describes the reflectance spectra or at least contains pre-calculated XYZ values for your chart. You can make one yourself if you own an (expensive) spectrometer, or you can download one. - a
.chtfile which describes the layout of the color target.
Both of these are available for the SpyderCheckr24 from Argyll.
My program of choice for creating DCPs from these files is DCamProf.
The resulting DCP can be used with RawTherapee.
