“Creating ICC profiles is simple as 1, 2, 3!
1. Photograph a ColorChecker Passport or any ColorChecker Classic in raw file format.
2. Process the TIFF file in Capture One using the recommended settings.
3. Use Camera Calibration software v1.2 to create your custom ICC camera profile for use in Capture One. Quit and reopen Capture One.
Your newly created ICC camera profile is now available and ready to use based on your specific camera and lens combination during your shooting session.”
