LightSpace Beta with New Pre-Roll Patch Sequence

A Piccy

As promised, the Pre-Roll feature is added to that new beta.

To reduce the initial drift slope you usually see at drift plot charts, the display has to work for some minutes (without the meter to measure anything) with a patch-set with average power for some minutes (before starting the real measurements).

Before the feature, for that procedure. the user had to start a profiling...then stop it after 5-15 minutes...and the re-start in...the added feature to do that automatically is called Pre-Roll, so you can import a custom cvs file of patch files you want and set how many seconds each patch to be displayed to the screen, after the end of that Pre-Roll patch list, it will start the selected (Anisometric for example) patch list and the meter will start measuring.

So you can create a custom patch list to be displayed for 5-15 minutes (for each display model the time can be different, its related about how the display is responding to the patch sequence average power).

This Pre-Roll can be used with Quick Profiles, as well as Characterisations.

For example, you can export 5-Point Cube Anisometric patch sequence in CVS file and then use it as Pre-Roll patch set.

LightSpace CMS 9.0.0.2830 (31 July 2018) has been released.

Release Notes

Added D65 versions of DCΙ-P3, ST2084-P3, and BBChlg-P3 colour spaces.

Fixed ST2084 'Save New' colour space issue.

Add Drift Patch colour selection option.

Fixed error with creation of Out Of Gamut LUT option.

Added CalΜΑΝ .3dl and .txt LUT formats.

Download Link: https://www.lightillusion.com/downloads.html

Note: All LightSpace related guides which are available online has been updated a lot of dates before the public release, to reflect changes the latest released version of LightSpace introduced.

All new features and developments are provided free to existing customers, continuing Light Illusion's approach of no additional costs or yearly support fees for all its software systems.

LightSpace_Drift_Compensation_Color

About Drift Patch Color selection option, it sets the patch color triplet to be used for Drift Compensation.

Normally this should be a relatively high brightness monochrome value, for example 85% Gray.

100% White is not recommended as the display may be clipping.

However, some displays can suffer excessive instability at high brightness levels (D-ILA projection for example), and so a lower value may be more viable.

Also, with PQ based HDR the patch value will need to be set below the clip point of the display.

Some SDR calibration RGB Triplets for various gray levels as quick reference you can use:

50% Gray: 128.128.128
55% Gray: 140.140.140
60% Gray: 153.153.153
65% Gray: 166.166.166
70% Gray: 179.179.179
75% Gray: 191.191.191
80% Gray: 204.204.204
85% Gray: 217.217.217
90% Gray: 230.230.230
95% Gray: 242.242.242
100% White: 255.255.255

Just some info about the upcoming Greyscale enhancement process; called as ''Augmented Data '; which helps reducing grey scale errors even further.

The Augmented data process enables the grey-scale information within a given profile to be 'augmented' with data from a totally different profile, effectively enabling the grey scale calibration to be altered and potentially improved.

For example, a relatively small Cube based profile, such as 10-Point Cube (1000 measured color points) could be used for a volumetric profile, and augmented with a 33 step Grey Only Quick Profile to enhance the grey scale accuracy.

The Augment process uses the LUT generated from the initial profile to pre-process the second 'Augmented' profile, enabling the Augmented Data to correct any inaccuracies in the original profile's grey scale, as well as enabling the use of a higher level of grey scale measurement granularity for enhanced accuracy.

Note: Although profiles of any type/size can be used as the Augment Data, a Grey Only Quick Profile is the most obvious to use. Additionally, using too many steps within the Grey Only profile (for example via a CSV file) can cause issues due to display/probe noise and instability. The 33 step Grey Only provided within LightSpace is the optimum for most Augment needs.

As always, using large profiles, Cube based or Quick Profiles, will greatly increase LUT generation times!

Augment Process

The process for using the 'Augmented Data process is as follows:

(Although, as with all LightSpace operations, there are no fixed workflows.)

1) Perform an initial Cube based profile of desired size (10-Point Cube for example).

2) Generate a LUT via Convert Colour Space.

3) Re-profile through the LUT using a Grey Only profile (33 step for example), or any other profile - Quick, or Cube based Characterisation. (The LUT can be loaded directly into the display/LUT box/Graphics program, or Active LUT within LightSpace can be used). The new profile will be 'saved' within the Manage Colour Space library, as normal.

4) Open 'Manage Colour Spaces' and select the initial Cube profile. Select the 'Add Aug Data' button, and from the pop-up menu select the second 'Grey Only' profile. The original profile will be modified into a new 'Augmented Data' profile, defined by the addition of a '+' to the Profile type.

5) Generate a new LUT via Convert Colour Space, with the 'Augmented Data' option ticked. (The new LUT will include the Augmented Grey Scale)

As always with all LightSpace operations there are no fixed workflow. The above is one example for the use of Augmented Data. Another could be to modify an older LUT with new Grey Scale data, rather than performing a totally new volumetric profile.

LightSpace's on-line manual has been updated already to reflect that upcoming new LightSpace feature. http://lightillusion.com/profiling_manual.html

We've found a couple of bugs!
(The Beta Testers obviously didn't do their job correctly...)

First, the 'LG' LUT Export format is missing from some licenses.
We'll get that sorted as soon as we can.
(But, we still do not know if the format as specified by Spectracal is correct...)

And, the new i1D3 EDR files are not installed correctly.

For now, please use the instruction here to manually add the missing files:
