ChromaPure 3.0.5 is now available for download

This release restores missing features and fixes bugs contained in the initial 3.0 release. It also adds some fixes for long-standing issues that significantly pre-date v3.

The following features have been added, restored, or enhanced:

DVDO Duo support is restored, including auto-cal

RGB and xyY Color Space modes are restored in the Color Management module

User images can be added to Custom Reports

An Application Settings icon has been added to the auto-cal screen

European users no longer have to manually adjust Windows regional format settings. ChromaPure now automatically forces U.S. formats for list seperators and decimal places regardless of the settings in Windows.

ChromaPure now will scale properly on high-resolution, small size displays without user intervention. This is a temporary fix because the application simply automatically adjusts the resolution of the display downwards so that text scaling is not required. This works but results in some loss of sharpness. A permanent solution will be provided in 3.1.

We have added a new item in the File menu called "Repair Settings". Selecting this will close the application, delete the settings file, create a default settings file, and then restart the application. Selecting this option will resolve many issues if instability is apparent.

The following bugs were identified and fixed:

Attempts to take measurements without initializing a meter did not display an error message.

When fL had been selected in the application, the report still showed cd/m2 in the Gamma modules.

Opening the Grayscale module, closing, and then reopening resulted in a benign fatal exception.

If the user failed to click Stop when in continuous mode and navigated to a separate module, continuous mode would still be active. Continuous mode now automatically stops whenever the focus changes from one module to another.

If the user clicked the Measure All button starting anywhere other than white, then the 90% point would measure multiple times.
Reports would not update data if the report module was already open.

A few tooltips were missing.

The Pre and Post-calibration data were switched on the final Advanced Auto-cal page.

Luminance correction was missing from the Contrast module.

ChromaPure 3.0.6 is now available for download

This small release addresses two issues that were important enough to fix now rather than waiting until 3.1. Please uninstall any previous 3.x version prior to installing 3.0.6.

The method for generating RGB values when using the 75% of Rec. 709 gamut has been changed. This pseudo-gamut can now be used throughout the application.

Some problems were identified and fixed in the Lumagen manual control toolbar.

To download see here:

ChromaPure 3.0.7 is now available for download.

It is free for license v3 users.

New Features

Added support for the 4K Murideo signal generator.

Enhancements

These enhancements involve making small changes that lessen the opportunity for error.

In Continuous mode, the user is now prevented from selecting other read modes until Continuous mode is stopped. Also, Continuous mode stops automatically whenever the user selects a different color. Continuous will have to be started again to resume readings of the new selection.

The i1D3 options panel in Application Settings has been removed and optimal settings have been hard-coded behind the scenes.

Bug Fixes

The following issues have been fixed:

When attempting to initialize a serial meter after ChromaPure has started, the system failed to update the list of available com ports.

The installation routine now requires the user to first uninstall a previous version of ChromaPure. Also, the application checks at runtime whether .Net Framework 4.6.1 is installed. If not, then the user is required to first install.

The Quantum Data 801 and 882 signal generators now generate the proper levels.

ChromaPure 3.0.8 is now available for download.

It is free for license v3 users.

New Features

Added support for the JETI 1501 spectroradiometer.

Enhancements

Enhanced support for JETI 1211.

Added user selectable wait times between generated test patterns.
Explanation: Some displays require some extra time to settle in after switching test patterns. This option allows to user to increase the default wait time. This feature is set to zero by default and should only be used in special cases when explicitly needed.

Added support for signal generator intensity in session files.
Explanation: If the user saves a calx file after taking measurements with a 75% intensity, then changes to 100% intensity (or vice-versa), continues to work, and then loads the saved calx file, reporting and dE calculation will be incorrect because they will be based on the currently-selected intensity, rather than the intensity used when the file was saved. With this build the intensity is saved in the calx file and restored when loaded.

The measurement order in the Gamma module is now high to low.

For those using a signal generator, when switching between modules the test pattern now updates to reflect whatever color is selected in the active module.

Bug Fixes

The data recovery feature was not working properly and could result in loss of data after a bad shutdown. This has been fixed.

Known issues

Switching rapidly between already-open modules using the navigation toolbar can result in a benign null fatal exception. Switching more slowly or using the tabs for navigation avoids this issue.

Please use DVDO Duo auto-cal with 100% intensity test patterns only. Support for 75% patterns will be restored in 3.1 when auto-cal in general will receive a substantial refresh.

ChromaPure 3.1.1 is now available for download.

Bug Fixes

The code that accommodates international regional formats was not included in the initial 3.1, which led to unexpected behavior on non-English language PCs.
Attempting to switch between the default tablet UI and vertical or horizontal versions of the traditional UI caused the application to shut down.
There was no intensity selector when the Calibration Disc mode was selected.
The Color Management module suffered from various types of instability and unexpected behavior.

ChromaPure 3.1.3 is now available for download.

Enhancements

We have simplified the X-Rite i1D3 initialization procedure. We have eliminated auto-detect and provided the user with the ability to select 25Hz, 50Hz, or 60Hz as the sync value.

We added degamma to HDR10 which allows ChromaPure to support HDR10 using external signal generators.

Bug Fixes

There was a cluster of problems regarding importing calx session files:
- 3.0.8 calx files did not import correctly. The gamut data in the CIE chart is still broken. This will be fixed in the next release. All other issues were resolved.
- When double-clicking calx files the application would open, but no data would appear.
- Imported calx files did not show average summary data.
- Imported calx files that contained auto-cal data prevented the user from accessing the data logs and full color information.

When clicking Measure All without having a meter initialized the system would generate a lengthy loop of error messages.
There was a refresh problem that occurred when changing Color Intensity. The values did not update in Color Management until the user restarted the application.

There was a refresh problem that occurred when changing the Reference Gamut. The saturations for the gamut did not update. NOTE: When changing the Reference Gamut you will lose all of the data from the previous gamut. If you want to keep this, save the data first or run a report.

Load and Save were missing from the classic UI.

The Signal Generator drop-down would not allow the user to access all of the test patterns.

UPDATE:

The "Lite" version of ChromaPure has been discontinued.

Until the end of February 2017, we are allowing existing ChromaPure Lite users to upgrade to ChromaPure Standard for $49 instead of the regular $100 price. After that time upgrades will no longer be possible.

This upgrade is eligible for older v2 versions ChromaPure as well. Upgrade for $49 and you'll get the latest v3 version of ChromaPure Standard, which is an additional $79 savings.

ChromaPure Standard offers support for 2 meters (instead of 1) and adds the following features to maximize image quality: Gamma, Advanced Color Management, ColorChecker, Reports, Auto-Calibrate, Lumens Calculator, Conversion Utility.

To upgrade your version of ChromaPure, visit our order page: http://www.curtpalme.com/ChromaPure.shtm

For more information on using these advanced features see our ChromaPure Grayscale & Color Calibration for Dummies guide: http://www.curtpalme.com/forum/viewtopic.php?t=35322

Cheers,

Kal

ChromaPure 3.1.4 is now available for download.

This release is free for licensed 3.x users. With this release we have stepped away somewhat from the bug fix cycle and focused instead on adding several useful enhancements and features.

New features

- The White Balance module now includes gamma information.
- Users can now select a Slow mode for the i1D3. Use this feature only when measuring black level, such as when measuring contrast. This is necessary because the default AIO measurement mode will not read below 0.01 nits.
- We have added support for the Quantum Data 780E signal generator.
- We have added a new gamma reference, HDR10 – Projector. Use this gamma target when calibrating front projectors using HDR10.
- The options module now includes a selection for Gamut Overlay. Select this option to see another color gamut superimposed on the reference gamut. This is useful when calibrating Rec. 2020. It allows you to see how the measured colors fit into other gamuts.

Enhancements

- The Built-in signal generator has been adjusted to facilitate easier use. Users no longer need to rely on a madVR utility to get proper levels.

Bug Fixes

- We have fixed data import problems with ChromaPure 3.0.8 data.
- We have fixed an issue that affected the user’s ability to scroll through the drop down list of individual test patterns for external signal generators.
- We have updated the Excel report to conform to the data structures of 3.1.x.

NOTE: DVDO Duo Auto-calibration will be released soon as part of 3.1.5.

Does ver 3 readout ft-L or do you still have to calculate from the "Y" reading?

How do you adjust saturation now?

Thanks, kal

I ordered the upgrade and disk from you. I still don't understand the saturation procedure. In the old days it was using red as a percentage of white or ????


Also, I have never been able to use the flashing bars for black level. Is it better to just use solid near black patterns?

This is the part that doesn't make sense:

"2.6.1.8. Adjust the display's main color control on the display until you have minimized the red error for red, green, and blue. The human eye is especially sensitive to red errors, so it is best to concentrate on this. "

How do you minimize the red error for anything other than red? (green and blue)?

thx

The point is that if you see errors for red, green, and blue and you cannot correct them all (which you can't with a Color control), then focus on getting red right.
