C1 (CaptureOne) does not support DNG profiles but ICM profiles. I just started to test the free ICC Color Camera Calibrator (CoCa) available at
www.dohm.com.au/cocad. The resulting ICM files work in principle with C1 but the correction of the wrong colors from K-30 DNGs is certainly a big effort. Perhaps you have to export in C1 the wrong color TIF files and use them in CoCa. Today I purchased a colorchecker classic test chart with 24 printed colors, so I am really at the beginning of a long journey.
I will report if I can achieve useful results.
Update: I was sucessful after really quick and dirty first trial. At night in Europe I had only a tungsten light for profile generation, but the result was already acceptable. I exported with C1 the visible bad DNG picture of colorchecker chart as TIF. After processing with CoCa the ICC profile is available in C1 and the colors look at least a little bit like reality when this profile is applied. The new profile is located at C:\Windows\System32\spool\drivers\color and available in C1 under "Other".
For two profiles see:
www.ey-com.de/captureone/k-30/, file "pentax_k-30_tungsten-test.icm" is just a test with the correct JPG file, but file: "pentax_k-30_tungsten-c1-wrong.icm" is a correction for the wrong colors of DNGs in C1 or any JPG/TIF exports from C1, which have not been modified before. Of course the color level is not correct (quick and dirty with Tungsten light) but the colors are no longer totally wrong in C1.
Of course I have some doubts that this procedure makes sense. After update of C1 for full support of K-30 such correction profiles will be useless. Until this update a correction ICM profile is only a unprofessional workaround, isn't it?
