[dispcalGUI-news] DisplayCAL 3.6.1 released

[Florian H. <fl...@di...>]

* [Feature] Adjustable hue preservation (values less than 100%
  will gradually hue shift very bright and saturated
  redorange/orange/yellowgreen hues to a more yellowish tone,
  preserving more saturation and detail) for HDR SMPTE 2084 3D
  LUTs with roll-off tonemapping (default 50%).
* [Feature] Ability to set a calibration target luminance by
  measuring the ambient light level.
* [Feature] Verification tab: Hold the “alt” key on your keyboard
  to create a profile or device link (3D LUT) self check report
  instead of a measurement report.
* [Enhancement] DCI P3 D65 profile for use as 3D LUT source
  colorspace or measurement report simulation profile.
* [Enhancement] Increased the default number of patches for the
  madVR HDR preset back to 425.
* [Enhancement] HDR 3D LUT SMPTE 2084 tonemapping: Restored near
  black tone reproduction for displays with non-zero black level
  and output offset less than 100% to pre-v3.6 values.
* [Enhancement] Improved HDR 3D LUT SMPTE 2084 tonemapping speed.
* [Enhancement] Improved HDR 3D LUT accuracy for colorimetric
  rendering intents.
* [Enhancement] Increased default display update delay for
  Resolve preset to 1000 ms.
* [Enhancement] Quantize Autodesk/Kodak (.3dl) 3D LUT values by
  always rounding up (match the format specification in the
  Lustre user guide).
* [Enhancement] Limit the number of concurrent worker processes
  depending on system memory to avoid swapping.
* [Enhancement] Always normalize CGATS data to Y = 100 when
  processing files not created by DisplayCAL.
* [Enhancement] Get the black level for computation of 3D LUT or
  verification target tone curves from the embedded
  characterization data if a lookup through the display profile
  returns zero (makes e.g. Rec. 1886 work properly in that case).
* [Enhancement] Synthetic ICC profile creator: Increase number of
  decimal digits for black level to 6 and do not clamp to 16-bit
  integer values to offer more fine grained control.
* [Enhancement]: Use configured XDG “well known” user directories
  (currently only used to determine the localized name of the
  “Downloads” directory).
* [UI] Moved HDR 3D LUT SMPTE 2084 tonemapping
  luminance/saturation/hue preservation controls to advanced
  options (hidden by default).
* [Moderate] madVR 3D LUT generation via the main application:
  When using a non-standard source colorspace whitepoint (by
  setting a calibration whitepoint target different from the
  source colorspace's original whitepoint, e.g. not using DCI
  white for DCI P3), non-standard values for input primaries and
  whitepoint were written to the 3D LUT header, madVR 3D LUT slot
  auto-detection for installation did not work if the source
  colorspace was not Rec. 709, and color conversion was affected
  if the 3D LUT was not installed via the madVR API (i.e. by not
  clicking the “Install 3D LUT” button, but choosing the 3D LUT
  manually in madVR's settings).
* [Minor] Downloads within DisplayCAL failed if the download
  directory didn't exist (regression of changes made in
  DisplayCAL 3.5, SVN revision 5081).
* [Minor] HDR 3D LUT SMPTE 2084 tonemapping for non-Rec. 2020
  source colorspaces did not work correctly (Rec. 2020 was
  assumed despite different choice).
* [Minor] Standalone 3D LUT maker: Don't unexpectedly switch to
  the source profile's gamma for simple gamma + matrix source
  profiles (e.g. DCI P3) when creating a 3D LUT.
