CalMAN 3D LUT Display Calibration – Software LUT File
CalMAN can also create a 3D LUT display calibration file for the HDLink Pro, without immediately loading
the file into the HDLink Pro. The HDLink Pro does not need to be available during this display calibration
and file creation process. The file created will be a .3dl file with the proper HDLink Pro data format for
later loading into the HDLink Pro with CalMAN (as detailed below).
To create a 3D LUT display calibration file for the HDLink Pro with CalMAN:
1. In the CalMAN main menu, select Open Workflow Template, then select the ‘Color Cube (3D
LUT)’ workflow.
2. On the CalMAN Display Control tab, connect to the SpectraCal Cube Generator as a Display
Control device.
3. On the Display Control tab, under ‘File Format,’ select ‘3DL – common .3dl formats.’
4. On the Display Control tab, under ‘File Path,’ select your desired destination for the .3dl LUT file.
5. On the CalMAN Source Settings tab, select your desired test pattern source for display
calibration.
6. Follow the display calibration instructions in the ‘CalMAN 3D LUT Display Calibration’ section
above.
7. On the AutoCal Setup popup dialog, under ‘Output Cube Size,’ select 17. Under ‘Bit Depth,’
select 10.
Done: Upon completion of the AutoCal 3D LUT calibration process, CalMAN automatically writes a .3dl
file, containing color cube display calibration data, to your selected file destination. This display
calibration file can be later loaded to an HDLink Pro, using the procedure in the ‘ CalMAN 3D LUT File
Load to HDLink Pro’ section below.
CalMAN 3D LUT File Load to HDLink Pro
CalMAN can load a properly formatted 3D LUT file into the HDLink Pro. The LUT needs to be a .3dl LUT
file with a bit depth of 10 bits and 17x17x17 data points, with the data points at the following bit levels:
0,64,128,192,256,320,384,448,512,576,640,704,768,832,896,960,1023.
This .3dl LUT file can be a display calibration LUT created with the CalMAN Cube Generator function (as
detailed above). Or, it can be a creative (look) LUT created by any other application (with the proper
data points). During the load process, CalMAN converts the .3dl file into the file format required by the
HDLink Pro.
To load a 3D LUT file into an HDLink Pro:
1. In CalMAN, on the Display Control tab, connect to the HDLink Pro as a Display Control device.
2. On the Display Control tab, click the ‘Open DDC Window’ button.
3. On the DDC Controls dialog, scroll to the ‘3D LUT Controls’ page.
4. Click the ‘Load LUT File’ button.
5. In the resulting file navigation window, select the .3dl LUT file that has been created for the
HDLink Pro.
Done: The selected 3D LUT file is now contained in the HDLink Pro.
