Dear disk users,

Using HCFR 3.2.0 with Ted’s LightSpace CMS Calibration Disk you will be able to measure now all the CalMAN Session of the disk Chapters, here is the complete list of the supported chapters:

For Ted’s LightSpace CMS Calibration Disk (Free Version) users:

CalMAN’s Color Checker Classic (24 Colors)

For Ted’s LightSpace CMS Calibration Disk (Full Version) users:

ChromaPure's 2/3-Point Grayscale
ChromaPure's 11/21-Point Grayscale
ChromaPure's Color Gamut (100% Saturation w/ 100% or 75% Intensity, 75% Saturation w/ 100% or 75% Intensity)
ChromaPure's 4-Point Saturation with 100% or 75% Intensity (25 Colors)
CalMAN's 4-Point Saturation with 100% or 75% Stimulus Level (25 Colors)

CalMAN’s Color Checker SG Fleshtones (19 Colors)
ChromaPure’s Color Checker (25 Colors)
ChromaPure’s Color Checker Skin Tones (19 Colors)

HCFR 3.2.0 follows the same pattern order with Ted’s LightSpace CMS Calibration Disk Chapters for any of the above measurement options and the HCFR’s 8-bit RGB Triplets for each pattern are matching exactly the RGB Triplets that the Ted’s LightSpace CMS Calibration disk has been encoded.

Below you can find the updated list of the total CalMAN and ChromaPure Chapters that any HCFR user can use to take measurements. These Disk Chapters are accurate and match the HCFR's Color Engine Calculations:



Instructions for x-Point Grayscale ChromaPure's Chapters Measurements

Uncheck ''use round down levels" that is located to HCFR ''Preferences'' -> ''General'' Tab. This is affecting only Grayscale measurements.

Instructions for Color Checker Chapters Measurements



Before starting the measurements you have to select from HCFR's Preferences -> ''References'' Tab -> ''Color Checker Patterns'' drop down menu list the selection of the measurement run you want to perform.

Select ''GCD'' if you want to measure using ChromaPure’s Color Checker Chapter.

Select ''ChromaPure skin tones'' if you want to measure using ChromaPure’s Color Checker Skin Tones Chapter.

Select ''CalMAN Classic'' if you want to measure using CalMAN’s Color Checker Classic Chapter.

Select ''CalMAN SG'' if you want to measure using CalMAN’s Color Checker SG Chapter.

Select ''CalMAN SG skin tones'' if you want to measure using CalMAN’s Color Checker SG Flesh Tones Chapter.

Instructions for CalMAN's x-Point Saturation/Luminance Chapters Measurements

To enable these measurements the users have to download the usercolors_pak.zip of HCFR.

By extracting the files of the HCFR's usercolor_pak, below are the Ted's LightSpace CMS Calibration Disk Pattern Sequences of the CalMAN's Session you can use with HCFR 3.2.0:



CM 4-Point Saturation (100AMP).cvs file for CalMAN's 4-Point Saturation (100% Stimulus Level) Chapter.

CM 4-Point Saturation (75AMP).cvs file for CalMAN's 4-Point Saturation (75% Stimulus Level) Chapter.

CM 5-Point Saturation (100AMP).cvs file for CalMAN's 5-Point Saturation (100% Stimulus Level) Chapter.

CM 5-Point Saturation (75AMP).cvs file for CalMAN's 5-Point Saturation (75% Stimulus Level) Chapter.

CM 10-Point Saturation (100AMP).cvs file for CalMAN's 10-Point Saturation (100% Stimulus Level) Chapter.

CM 10-Point Saturation (75AMP).cvs file for CalMAN's 10-Point Saturation (75% Stimulus Level) Chapter.

CM 6-Point Near Black.cvs file for CalMAN's 6-Point Near Black Chapter.

CM Dynamic Range (Clipping).cvs file for CalMAN's Dynamic Range (Clipping) Chapter.

CM 4-Point Luminance.cvs file for CalMAN's 4-Point Luminance Chapter.

CM 5-Point Luminance.cvs file for CalMAN's 5-Point Luminance Chapter.

CM 10-Point Luminance.cvs file for CalMAN's 10-Point Luminance Chapter.

Note: The pattern sequence of CalMAN's 10-Point Luminance is identical to the Color Checker Selection ''RGB Luminance Axis'', so it can be selected from the drop-down menu available @ HCFR's Preferences -> ''References'' Tab.

These new measurement selections currently are now available to the HCFR's Color Checker Pattern drop down menu. To enable any of the measurement option the user has to rename the CMxxxxxxx.cvs measurement file want to perform to usercolors.csv and place it to the same folder where the HCFR has installed (where the HCFR's executable is located), and select from the HCFR's Color Checker Pattern list the ''User defined'' option.



This can be performed while the HCFR is running, for example to do one measurement run; and then replace the CVS file to load the new colors set... and hit the delete icon next to the grid.

For being more user friendly, If there much interest from the HCFR users that using Ted's LightSpace CMS Calibration disk; then these measurement options will be probably selectable from the Color Checker's drop down list in a future release of HCFR. You can request this from Zoyd, the current developer of HCFR to this thread.

Note that there differences between the RGB Targets of CalMAN vs. ChromaPure ColorChecker & Skintones or Saturation patterns.

Thanks Zoyd (current developer of HCFR) for adding these new measurement options for Ted's LightSpace CMS users of HCFR.
