The Advanced Technology behind Light Illusion's colour science is second to none.
Light Illusion's colour management systems have been developed around the most advanced colour mathematics engine used within any colour system currently available. As such, all Light Illusion systems operate in a totally unique way, providing final results that far exceed those of alternate systems, combined with far greater tools, options, and capabilities.
ColourSpace 3D LUT Calibration
Traditionally, the calibration process is directly linked to the profiling/measurement process through the use of calibration workflows, restricting the level of accuracy attainable.
ColourSpace uses a non-structured approach to calibration and colour management, maximising the attainable accuracy in each separate process.
Internally, ColourSpace works to a very hight level of granularity, further improving the accuracy of any final LUT generated, and is not limited to grid based data sets enabling users to define their own profiling sequences using any approach they choose.
Advanced Mathematical Profiling
As ColourSpace performs all its calibrations with a true mathematical based colour engine, without the need for a guesswork/iterative based approach, the data generated is a direct profile (or colour map) of the display being calibrated, with no virtualisation, iterative re-reads, or need to re-verify measured points during profiling.
ColourSpace is a true single pass closed-loop profiling system, with the ability to generate multiple target colour space calibrations from a single profile pass.
ColourSpace has advanced options options for LUT processing, as well as the world's most advanced Colour Engine, which uses totally unique mathematical algorithms for the calculation of the final calibration LUT from measured profile data.
The calibration results attainable via ColourSpace are far superior to any alternative calibration systems.
Total Image Chain Calibration
As ColourSpace can be used in closed-loop calibration mode, or Display Independent Profiling (DIP) mode (both fully automated), it can uniquely calibrate not just the display, but the full image chain to be used for viewing - critical in Home Theatre environments, where the DVD/Blu-ray player is a key component in the image chain, and often outputs a signal that is not bit-perfect, and so needs to be in the calibration chain for complete final image accuracy.
Calibration system that link profiling to the final calibration, using guesswork/iterative feedback loops cannot perform such DIP based calibrations.
For more information on ColourSpace disc based DIP calibration see Ted's fantastic LightSpace CMS Calibration Disc at www.displaycalibrations.com.
User Profile Patch Sets
Very uniquely, ColourSpace is not restricted to pre-set patch-set for profiling, and users can define their own profiling sequences as needed.
Such sequences can give very high levels of final accuracy, with far smaller patch sets, so in far quicker time scales, with a high level of final calibration granularity.
This ability for User Patch Sets is further enhanced within ColourSpace with the ability to import patch sets specifically tailored to home TV's internal CMS patch requirements for manual calibration, regardless of the patches needed.
High Volumetric Accuracy
Using a high level of volumetric granularity means that the acquired display profile is capable of dealing with any issues that a given display may be suffering, including any non-linear volumetric errors; tracking errors; RGB crosstalk and separation errors; colour gamut errors; etc.
Having access to full volumetric data means ColourSpace can assess exactly what impact each and every colour point has on the final calibration, enabling all display errors to be corrected within the final calibration LUT.
The Hint process within ColourSpace extends this capability, enabling small patch sets to generate 3D LUTs with a far higher level of volumetric accuracy than would otherwise be possible.
Unrivaled Speed for Unrivaled Accuracy
Through the capabilities of the advanced Colour Engine within ColourSpace, the time taken from initial profiling through to final 3D LUT calibration is far shorter than via any alternative calibration system.
When combined with capabilities such as Hint and Augment Data, high-accuracy 3D LUT calibration can be performed in exceptionally shot timescales. Ideal when in time-pressured environments that are still colour critical, such as on-set DIT work.
ColourSpace can calibrate to any given colour space, with any target Gamma, including all standards, such as Rec709, BT1886, P3, etc, all without the need to define your required target before profiling, enabling you to interactively try different results.
Additionally, the ability for ColourSpace to work with user defined Parametric Gamma values is unique, and enables users to set their own intricate target Gamma values, allowing, for example, advanced control of display blacks, which is very useful when needing to overcome less than ideal viewing conditions.
No Unnecessary Additional Processing
Generating a true profile data-set of the underlying display parameters, totally separately to the actual calibration, enables far more accuracy, combined with a large range of options associated to final calibration, LUT manipulation, Look and colour management, and more.
Having an unadulterated measurement data-set means there is no need to apply unnecessary third stage data manipulations, as the total volumetric colour space has been assessed to a level beyond the need for such separate adjustments. For accurate final calibration, every colour point in the volumetric space MUST be considered equal, not just grey scale or primary colour groups.
A classic understanding of this is skin-tone - as it is neither associated with grey-scale nor primary colours, but human visual acuity is quick to spot poor skin-tone accuracy.
Advanced Look Management
Depending on the version, ColourSpace includes a range of LUT manipulation and effects tools, ideal when generating Looks, rather than when performing calibration.
When performing calibration, the only time any manipulation is needed is when the probe in use struggles to read valid data, specifically within the blacks/shadows. ColourSpace has tools to manages such issues as required, maintaining an accurate level of final calibration.
However, many 3D LUTs are used for Look Management, for example for on-set viewing of Log images with different Looks applied.
ColourSpace has a range of tools to enable creative Look LUT generation, taking Colour Management beyond direct calibration.
Very uniquely, the internal colour management engine within ColourSpace has been developed to generate the most accurate possible film emulation LUTs, traditionally used within Digital Intermediate grading operation to perfectly match the digital display to the final Celluloid film projected image.
This capability shows just how good ColourSpace really is, because film has excessive non-linear response, poor decoupling (crosstalk), poor tracking, and generally the most messed-up colour space imaginable! As a consequence, few calibration system have what it takes to accurately generate true Film Emulation LUTs that accurately match the final projected film image.
