If you compare that 2 reports you will notice differencies.
This is a known and reported issue that CalMAN's AutoCAL proccess that users have already reported, it's not something new.
Sorry but my understanding is If this is true, that the calibration of one color interacts with other colors in the cube, the Light Space concept can´t work.
To give some more detail about the LightSpace Software, because i believe maybe a lot of users here think that is a new software that entered the HT market late 2012....
Lightspace comes from professional market and it's used @ post production houses from 2009 only for 17-Point Cube (4913 Color Points) Profilings since that is the Stardard Cube Size for Critical Color Applications @ Professional World.
Color Scientists from Professional World has decide for that numbers of Color Points (4913) before a lot of years, this is the Default Cube Resolution @ Post Production Studios, they don't accept lower color points.
Think that they have decide for that 4913 Color Number for the Post Production Displays they are using which the cheapest model costs around 20.000$.....these post porduction displays have the best technology available and they have very linear/stable response.
The Question here is why they used so many colors as a default and not 778 or 1500 as they working only with the best available displays?
If the professional displays of 20-50.000$ needs 17-Point Cube Profling, Our Consumer World Displays will need 17-Point Cube as a minimum!
LightSpace gives you the option to run a profiling from 3/4/5/6/7/8......17-Point Cube but only the 17-Point is recommended.
I have Evaluate THX CineCube HD also, It has 2 Options for Cube Resolution: Quick Profiling (1000 Color Points) and Full Profiling (4913 Color Points).
Seperating Profiling from Calibration is the way that the 3 major Software Companies from Professional World are using, THX CineCube HD, FilmLight TruLight & Light Illusion LightSpace CMS.
LightSpace's Chief Colour Scientist is the same person that developed the Colour Pipeline for Industrial Light & Magic (ILM: George's Lukas Motion Picture Effects Company
), WETA Digital (Peter's Jackson Visual Effects Company
) & Park Road Post (Peter's Jackson Post Production Facilities
). Their Chief Colour Scientist was also responsible for the colour science in TrueLight.
LightSpace is already installed at the most popular Post Productions Facilities
around the world, including Warner Bros, Universal Studios, Walt Disney, Dolby, BBC etc...
I found your statement 'the Light Space concept can´t work' very funny after reading your post, since I have experienced the difference of using LightSpace (using it 4 months already).....also used CalMAN/ChromaPure for the last 3 years.Edited by ConnecTEDDD - 3/31/13 at 6:48am
