I have an Xrite i1 Pro that I purchased from Amazon a couple years back and Chromapure 2.x with Autocal licence. I am not sure if I should upgrade to Chromapure 3.x or get LightSpace as that has been talked about a bit in this forum. Does LightSpace have an Autocalibration feature? There's several versions, which version works with the Radiance Pro?
If you have X-Rite i1PRO (Spectrophotometer) then you will need to get the X-Rite i1Display PRO (Colorimeter) to be able to take measurements for 3D LUT (because stand alone i1PRO is slow and poor at low light measurements), you will use i1PRO as a reference to create a meter correction table (which will improve the colorimeter color accurancy) while i1Display PRO is a lot faster and very good at low light measurements, so having both meters it's be best combo for any home calibration enthusiast.
LightSpace is the oldest software in the market which designed for 3D LUT display characterization, think that they were involved in pro area for 3D LUTs from 2009, no-one knew at HT area that time what was a 3D LUT....ChromaPure released @ August 2009 while CalMAN had version 3.0 out that time
So when LightSpace was creating 3D LUT profilings for thousand color points for movie/film industry (with 1 meter read per color) the same time ChromaPure/CalMAN has able only to measure (graphical presentation what meters was reading, dE calculation, generate graphs from reading) of 11-point Grayscale and simple Gamut readings (6 colors only, RGBCMY).
These facts show exactly how advanced color science LightSpace had before a lot of years for 3D LUT's and can guarantee you professional level of final results.
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; as you can see there's a large amount of colour science knowledge behind the LightSpace's Engine.
LightSpace is reading one point one only time, so for a 4913 color point 3D LUT it takes 4913 meter readings for example, doing this... LightSpace will know better how your projector/display is responding and about what colors can display and created a virtual model of your display to feed it's engine... The more points you feed it's engine, the greater idea of what your display is capable and what corrections can be applied, so LightSpace generates a correction 3D LUT table at once for all color points together, so it counts linearity of the correction, more smooth, and with better final results, and it will avoid to try to fix something that can't fixed or try extreme corrections to get you low dE somewhere but not good result later validating visually etc.
When you finish the measurement with LightSpace it saves one measurement data file. You use that file to generate the colorspace correction 3D LUT tables. The correction generation takes about 2-3 seconds only. For example you can generate different corrections in a few seconds, with different gamma, for example one correction with 2.2 Gamma, other with 2.3 Gamma other with 2.4 other with BT1886, so from one measurement run you can generate as many colorspace conversion you like, with different gamma values, without needing to take new measurements. When a newer version of LightSpace will be released and you see that at it's release notes the colorspace engine is improved for example, you don't need to take new measurements....you just install the newer LightSpace version, you opening your last measurement data file and you generate the new corrections.
Additionally from November 2016, LightSpace has added HDR Multiplier feature for HDR Projection and custom roll-off parameters which a lot of Lumagen PRO users are using already for HDR 3D LUT generation for projectors. All that time no other calibration company has something to offer similar, this is why LightSpace is the only choice for Lumagen PRO users which work as expected.
The correct license level where you can use any Lumagen processor and i1Display PRO, i1PRO1/2 is the LightSpace HTL, you can contact me for more details here: http://www.displaycalibrations.com/contact_us.html
BTW, there no annual fees for updates with LightSpace, there always free.
