+Error extracting color patches

In most cases if you see the message that the ColorChecker Passport software has an error extracting color patches you have one of the following scenarios.

  • The ColorChecker Passport is too small in your selected image for the software to have enough pixel information to create an accurate profile.
  • Your image is slightly overexposed, causing the luminance level on some of the lighter color patches to be equal to or higher than the white patch. When this happens, the calculation that determines the location of the patches becomes confused and cannot detect the patches.
  • Your native Raw file has an internal rotation that is affecting the automatic patch detection in the Lightroom plugin. This is a known issue with some camera bodies, particularly the PhaseOne P65+. This error is scheduled to be addressed in an upcoming revision of the Passport software. In the meantime, you can work around this problem by exporting a DNG file from Lightroom and creating a profile in the ColorChecker Passport standalone software.
