I am announcing ChromaPure 2.1.

This is a significant upgrade, in many ways even more profound an upgrade than 2.0. Upgrades for 2.0 users is free. 1.x users can upgrade for $59.95.

You can go to the News section of the ChromaPure web site for Release Notes. You can also go to the Demos page for live examples of how some of the new features work. A new user's manual will be posted this weekend.

ChromaPure 2.1 will be available for download on the News page in just a few days.

Since we have completely re-engineered the way we correct a field meter's response with a reference meter, those with PRO meters will have to be issued new license files. It will take me 7-10 days after release to finish this. In the meantime you can use the application, but the corrections built into your license file will not function and you will get the meter's native response.

 Gamma. This performance parameter describes how the display
responds to increasingly more intense signals. As a signal gets more
intense, if the display rises out of black very fast, then it has a low
gamma
. If it rises out of black slowly, then it has a low gamma. The
optimal gamma is expressed numerically. Aim for a gamma in the 2.2-
2.35 range. For more information on adjusting gamma in ChromaPure,
refer to Setting Gamma, p. 59.

Both low?

Tom, I was looking at the new Demos, and I do see the the Meter Offset procedure looks simpler--not having to exit the program. But I see that one is now taking the readings only at R, G, and B, and not all 6 colors as previously. Am I understanding this correctly?

Also, does having the Pro version allow one the FW upgrade gratis?

I'm glad someone asked this because it is worth spending some time explaining.

In earlier versions, we applied corrections at seven points: white and the pri and sec colors. This was necessary because the corrections were simply linear offsets. For example, if the test meter measured white at x0.309, y0.325 and the reference meter measured x0.314, y0.331, then an offset of x0.005, y0.006 was applied. This would be repeated for all pri/sec colors. The advantage of this approach is that it is simple. The downside is that it only works with the sampled colors. As long as we were measuring only 7 colors (white and pri/sec colors), this is fine. However, when I decided to beef up the advanced color management module, this approach would no longer do. A linear offset applied to red, simply would not work for a red that was, say, 50% saturated.

Thus, I felt a need to replace linear offsets with 4-color matrix calculation, which works for ALL colors and white. I was reluctant to implement this because it requires an almost absurdly complicated formula. I had to ask Greg Rogers for some help just to get the implementation correct. In fact, other than perhaps the CIEDE2000 formula, this is the single most complex mathematical operation in the entire application. Every reading has to be processed through 15 discreet steps to get the correct result.

Since ANY color can be derived from some combination of RGB, sampling the secondary colors is unnecessary. White needs to be sampled because the formula needs to calculate the amount of white in each color. As everyone who has done CMS and grayscale knows, the color gamut does not predict white balance.

For existing 2.0 users with PRO meters, I will be sending out updated licenses over the next couple of weeks that use the new matrix method. Please be patient. This is very labor intensive and will take time. My current priority is resolving some last-minute issues so I can make the application available for download. If you have a regular non-PRO meter, then a new license is not necessary.

For those interested in the 4-color matrix method, see
http://citeseerx.ist.psu.edu/viewdoc...=rep1&type=pdf
for reference.

Tom, I have an Epson 6100. As you may know, the best way to calibrate these Epsons is to use 75% saturation patterns. Colors end up being oversaturated at 100% this way, but 75%, 50% and 25% line up great. If you calibrate to 100%, everything 75% and below are woefully undersaturated, so using 75% saturation patterns is way better (I use the AVSHD disk).

In your new manual, you say this:

"The Advanced Color Management module will also
help you to determine if perhaps you should calibrate your color using 75%
saturation targets. You may use the standard Color Management module for
this. For more information, refer to Using Color Management, p. 51."

How do I use the standard Color Management module for this? Do I just use the 75% saturation patterns when doing my baseline readings then use the module normally? Do I ignore the colored chart altogether and just follow the numbers in the table as I change the HSL settings? It would be great to use the percentages in the colored chart instead of the tables.

The Color Management module requests the gamut you will calibrate to. In this release I added 75% Rec. 709. The module works the same as usual. It just expects 75% of Rec. 709 as the targets. You can use DVD test patterns, the ChromaPure internal test patterns, or an external signal generator that supports these colors, such as the AccuPel DVG-5000.

Excellent addition! That will make calibrating to 75% sooooooooooo much easier.

Would I use a 75% white pattern as well in the CM module, or 100% white, then 75% for primaries and secondaries?

White is 0% saturation by definition. Use whatever level of stimulus for white that you use for the colors. The internal CP 75% saturation test patterns are 100% stimulus.

2.1 will not install without doing the uninstall first - same as the last update.

Ran trough all modules in 2.1, looks great.
Also loaded some previous exported calibrations and all loaded and displayed properly.

Good job Tom.

Tom, I have found a bug with the new version of Chroma Pure 2.1 and the Lumagen Radiance.

I have selected 75%-Patterns with the Radiance. In the color gamut window Chroma Pure uses a 100%-Pattern for magenta, instead of 75%. So the luminance error is about 80%. That's only for magenta, the other colors use 75%.

Please correct it.

Another thing: i must use "one" as stop bit with the Radiance. Otherwise Chroma Pure is crashing.

Thx !

Yes, "none" is not a valid choice, so use one.

I'll look into the Radiance pattern issue.

Hi Tom !

And have also a look for "empty" boxes like in the "Lumens calculator": let all text boxes empty and press "calculate". Then Chroma Pure crashes. That's the same for nearly all other text boxes too ...

Not sure if this is correct or not but when I use my Radiance Mini3d as a Signal Generator in 2.1 Chromapure uses the Radiance Reference patterns rather than the Adjustable ones. This means that when I come to calibrate my sources the results are quite different.

It would seem to me using the Adjustable patterns would be better ? If I use the Adjustable ones the readings are almost identical to using a calibration disk in my BD Player

Yep, that's an old problem of Chroma Pure using the Radiance. It's the same for the Radiance XE. I thought, Tom has corrected it with 2.1, but unfortunately he didn't.

At the moment you should select the patterns manually instead of using the automatic. Also measuring the gamut doesn't work. Try to use the automatic and use 100% and then 75%: Chroma Pure isn't able to select the correct percentage of the patterns. That's very annoying.

So far, I prefer CalMAN. I like Chroma Pure too, but there is a lot of work to do with it. And I won't spend my time with selecting test patterns manually when CalMAN is able to do it for me.

I am also waiting for the automatic calibration in Chroma Pure which should be released in fall 2010. Again, CalMAN is the better choice at the moment: the automatic greyscale and gamma calibration works nearly perfect.
