Apple Color 1.5 - Manual (Page 158)

2 Load a good evaluation image (such as a Macbeth chart) into the Timeline.
3 Display the same image on the target display using a second reliable video source.
4 Open the Primary In room and adjust the controls appropriate to make the two images
match.
5 Choose File > Export > Display LUT.
6 When the Save LUT As dialog appears, enter a name for that LUT into the File field, choose
a location to save the file, and click Save.
By default, LUTs are saved to the /Users/username/Library/Application Support/Color/LUTs
directory.
Important: If your project is already using a LUT when you export a new one, the currently
loaded LUT is concatenated with your adjustments, and the combination is exported as
the new LUT.
Using LUTs
All LUTs used and generated by Color are 3D LUTs. Color uses the .mga LUT format
(originally developed by Pandora), which is compatible with software by Rising Sun
Research, Kodak, and others. If necessary, there are also applications available to convert
LUTs from one format into another.
LUTs don’t impact processing performance at all.
To use a LUT
1 Choose File > Import > Display LUT.
2 Select a LUT file using the Load LUT dialog, then click Load.
Note: By default, LUTs are saved to the /Users/username/Library/Application
Support/Color/LUTs directory.
The LUT immediately takes effect, modifying the image as it appears on the preview and
broadcast displays. LUTs that you load are saved in a project’s settings until you specifically
clear the LUT from that project.
To stop using a LUT
µ
Choose File > Clear Display LUT.
To share a LUT with other Color users, you must provide them with a copy of the LUT file.
For ease of use, it’s best to place all LUT files into the /Users/username/Library/Application
Support/Color/LUTs directory.
