Clearly I am a rank beginner just exploring the possibilities of using DCamProf to create better camera profiles (DCP).
I was motivated by the relatively new page in RawPedia (cited in the first post above). After taking the first few steps in my journey, I have a question. Given the rather underwhelming response to the above post I am uncertain if I should continue to post in this thread but, finding no better spot, here goes:
I made a raw image of the Color Checker Passport, opened it in RT, Neutral profile. Cropped the image to just the color patch page of the Color Checker. Ensure the black patch is positioned at lower right. In Color Management tool: click “Save reference image for profiling”; apply white balance NOT checked. Resulting image file name: CCPP.tif.
Next, using the ArgyllCMS software, I proceeded to create a .val file (just as a sanity check). This file should contain the RGB values for each of the 24 color patches. Opened a command prompt in the folder containing the tif image.
scanin -o -dipn CCPP.tif ARGLREF\ColorCheckerHalfPassport.cht diag.tif
the resulting output files: diag.tif when opened showed perfect alignment with no errors or problems…
The file CCPP.val gave R, G & B values for each of the color patches
The PROBLEM: The RGB values shown by the file did not come even close to approximating the reference values for the ColorCheckerPassport derived from several online sources. Is this to be expected? If not, where have I gone wrong?
