Although not something I use every day, making DNG profiles is a good way of working round awkward lighting conditions, where the trouble of making a full icc profile is perhaps not merited.
X-Rite have now announced some free software (available when registering a colorchecker passport):
ColorChecker Passport DNG ProfileManager (Mac and PC)
Key features (from X-Rite)
- Provides a single list of all installed DNG profiles
- includes non-printing image data such as file name, camera, light-source(s), and creation date
- filters by camera
- sort by any column header to locate or correctly rename profiles (both internal and external names)
- easily enable/disable profiles to prevent profile overload
- quickly collect and export DNG profiles for backup or distribution
The software displays current profiles available – some Canon 1Ds3 ones I had in use are shown.
It’s also possible to rename and export files (they normally live in a specific place)
There is also a video available for download, that shows more about how to use the ColorChecker Passport.
