Just for the fun of it I ran some tests comparing 17^3 profiling and calibration, with a Quick Profile and calibration - all with the i1D3.

The 17^3 took 1 hour 20, and the QP 2 mins.

The results were rather interesting, with very little difference - both in the numbers and visually.
The display was a 'standard' LCD TV with acceptable RGB Separation, but does show what can be done with a very quick calibration process.

See: http://www.lightillusion.com/calibration_speed.html

Personally, on this display I normally use a 21^3 profile and calibration, as it takes just 2 hours 30, but it was an interesting comparison.

Hi Steve,
I was looking at the graphs on your link and it occurred to me that if your RGB seperation is that good to start with, why do a LUTs calibration? Isn't the main benefit of a LUTs calibration to correct for the non linearities?

Displays: Samsung 64F8500, Panasonic 65VT50, Oppo 95, Pioneer 51, Tivo Roamio and Mini, Dish VIP722.

Hi Jim,

That's a good question, and the simple answer is that while the display screen may have a 'linear' response to a change in input signal, very few in-built display colour management systems are themselves 'linear'.

This means the display's cms will introduce non-linear inaccuracies.

Unfortunately, this is all too common.

Also, the granularity of a 3D LUT is far greater across the full volumetric space than any display cms.
(Basically, in the example on the website page you have 17 point control over Red, Green, Blue, and Grey Scale, with the volumetric correction calculated between them - that is just no possible with basic display controls).
That will always produce a better final calibration.

Steve

LightSpace CMS 6.6.7.2061 (24 March 2015)

Light Illussion has just released the Next Generation of Color Mathematics for it's advanced Color Engine, which is at the heart of the unparalleled calibration accuracy of LightSpace CMS.

The original Color Engine had previously proven to be the most accurate, as well as the fastest available for display calibration, LUT generation, LUT conversion and LUT manipulation. However, nothing is ever perfect, and Light Illusion knew they could do better. After over 6 man-months of work the algorithms and mathematics that are at the core of the LightSpace Color Engine have been totally re-written and enhanced, with visible and measurable improvements in final calibration results.

Note: for users that have performed a recent display profiling, they don't need to re-measure again their displays. It's required only to install the new LightSpace version, load their measurement file and generate the ColorSpace conversion to get the new 3D LUT correction file and then upload it to their 3D LUT hardware device or to their 3D LUT capable monitors. This saves a lot of time.

Full Release Notes @ available here.

This version includes:

-- New Colour Engine mathematics and algorithms

-- New LUT Format for Canon 4K Professional Displays

-- Changed operation of VideoScale functions

-- Changed defaults for Convert Colour Spaces

-- Added Differential Gamma graph

-- Added support for DVDO AVLab TPG patch generation

-- Corrected Active LUT effect on initial patch in Measure mode

-- Fixed error with Probe Settings not being remembered correctly

-- Small changes for CR-250 integration

-- Added error message if CDL/CCC file invalid

-- Corrected minor Convert Colour Space white loss

-- Changed UHDTV label to UHD Rec2020

-- Added ST2084 Gamma profiles for Rec709, Rec2020, and P3

-- Fixed error with Hubble probe connection

-- Fixed duplicate LUT being applied to Ref Image when exporting Arri Looks

LightSpace CMS 7.0.0 is coming….

For LightSpace users, there some real interesting new features like these ones you can see below:

Quick Profiling

Additionally to the Quick Profiling of Primary/Secondary Colors measurements that were available since now, Gamut Saturations @ 75% or 100% Stimulus Level and Memory Colors (Color Checker Classic) options added, to quick overview the performance of any display.



Here is an example of the CIE chart after the Memory Colors measurement:



Gamut Triangle Level

The new Gamut Triangle Level function enables the visualization of a display's gamut at all matched RGB primary points throughout the full stimulus range. By cycling through list of available matched RGB primary points it is possible to see the shape and size of the Gamut, and see at what levels it is smaller or larger that the desired target.



When you will run a Quick Profiling of Primary Colors which measures 20-Point of Luminance per color channel @ 100% Saturation, you will be able later to check the 100% Saturation of any Luminance level to overview the gamut coverage triangle over these 20-Point Luminance levels to check if the gamut coverage remains the same or if is reduced; to find which pre-calibration settings give the largest coverage etc.

This is extremely helpful when it comes to understanding the underlying capabilities of a given display.

Stimulus Levels



The Stimulus Levels function is another of the 'filters' for the CIE graphs, and defines how the measured points are shown. As with all the points filters they are additive options, and will combine with any other filters selected. The Stimulus Levels filter will show any and all points that include the selected value within any R, G, or B stimulus data. This enables easier selection of a given point to enable it to be isolated via a double click to see the points associated measured color data and Delta-E values.

Delta-E

You can display at the CIE Chart only the colorpoints with the selected dE range, to check what areas of the display have more errors.



The Delta-E filter is also another of the 'filters' for the CIE graphs, and defines how the measured points are shown. As with all the points filters they are additive options, and will combine with any other filters selected. Therefore to see just the points within the available Delta-E ranges first disable all other filter tick boxes. The benefit of this filter function is that it enables a quick assessment of the spread of Delta-E values within the measured profile, allowing a very quick understanding of the overall accuracy of the display.

Reports

The new Reporting feature enables a .pdf export of the various graphs, as well as details on various aspects of the selected profile, including Luma range, contrast, Delta-E ranges, etc., as well as user editable sections for client name, display, probe data, and more.
