ColorChecker Passport software has the ability to allow users to give the profiles custom names that are camera and lighting condition specific. If you are trying to create a profile but the name will only show as "Profile.dcp" and not allow you to give the file a custom name you are working on an older version of the software. This was an issue that was resolved in version 1.0.2.
To update to application either use the "Check for Updates" feature built into the software or use the link below:
