MAKING SENSE OF COLOUR MANAGEMENT...

The LightSpace CMS Profiling & Profile Management option is probably the most important component of the system, enabling fully automated display profiling with a supported probe, and automated LUT generation from the generated profiles.

The process is very easy to understand, and is initiated from the Display Characterization menu. When selected this menu opens a window to allow selection of the cube size to be profiled.

Select the size of the profile to be performed, and the time for each patch to be displayed, and when activated each flat will be presented in turn and measured, using the network Java App if required.

For Display Independent Profiling profiling of a display that cannot be connected to the LightSpace CMS PC directly or via a network connection (an SDI driven system for example) the software provides for the calibration flats to be exported as a dpx sequence of frames. These frames need to be made into a sequence with a duration for each flat equal to the value set on the Display Characterization interface, and run in close sync with the main software generated flats.

When 'Measure' is selected a Calibration Area window will be displayed, which can be re-positioned and re-sezed as required, along with a Calibration Status window providing real-time feedback on the measured colour values as well as a percentage complete thermometer.

When profiling is complete the profile will be saved in the 'Manage Colour Space' menu, and can be accessed via the 'Manage Colour Space' button.

To automatically build a LUT from the generated profiles select 'Convert Colour Space' from the 'Tools' menu, and select the profiles (colour spaces) to match to/from.

The above image shows a calibration LUT being generated to match a display to a film lab using Kodak 2393 print stock. The display was profiled using 4913 patches! Eeek indeed!!!

When the LUT has been generated the standard tools of LightSpace can then be used as necessary to modify the LUT. See the LightSpace CMS Manual for operational instructions.
