When you cintrol the lumagen from within chromapure with the new control toolbar, you can use clicks, which are .5 increments, or you can highlight the value and enter it manualy with whatever number you like, also meaning .1 increments. You can find a demo on this on the chromapure demo website.

Jeroen1000:

I found solution to resolve international settings for CP to work correctly for all reports (including Excel).
Leave Language as is (mine is Slovak)
Open regional settings and set following (I attached snapshot from my other PC for reference in english language for better understanding)

Decimal symbol set to "." (point)
List separator set to "," (comma)

In recognition of this, we need to change the order in auto-cal as well. I already have this in beta, so it should be released in the next day or two.
This is a great news....can't wait to see this. smile.gifsmile.gifsmile.gif

Lets go Tom, I want to calibrate this weekend! smile.gif

Does the new Color Checker module presume a certain gamma?

If so, what is it?

Is there an automated process that will programatically make and report all the measurements or do we make them one at a time as it would appear?

This issue is more for 8-point users than 125-point, which re calibrates grayscale at 4 points in any case. While you are waiting, why don't you try the new Lumagen control toolbar? I think that you'll find that you can do a calibration this way manually very fast (15-20 minutes). Use the toolbar with the White Balance module for grayscale, Color Management module for color, and the Gamma module for gamma. Check your work in the Post-Calibration Grayscale and Color Gamut modules.

Good question. Yes, it assumes a 2.2 gamma. Anytime you convert from RGB to xyY or vice-versa, you must have a gamma (or degamma) value.

Currently, you have to make them one at a time.

Is this a feature request? If so, be as specific as possible.
post #4058 of 5348
Would it be possible to use measured gamma when you determine/calculate the target within chromapure?

Yes, this is the correct procedure.

I think that Jeroen1000 wanted something in CP that would render this step unnecessary.

It would be possible I guess, but I don't think it would be desirable. What would be a better idea is perhaps a gamma selector that allowed other choices beyond 2.2.

That's right. You don't have to use the spinners. You can always click inside the box and type any manual change you like. This is useful for making unusually large or unusually small changes.

yes, ideally the same selection values for all modules (gamma, auto cal, color checker, etc)(including BT.1886).

This sounds awesome....I'll definitely give it a tryout!!

OK, I have uploaded a 2.4.1 beta at

http://www.chromapure.com/distribute/beta/chromapure.zip

This just addresses the issues discussed with auto-cal (visibility of controls and the 100% calibration).

1. Pre-calibrate 100% using the display's own RGB white balance controls and CP's White Balance module. This will just take a minute or two.
2. Set auto-cal to reset settings to default (this generally provides better results).

The only change to the auto-cal routine we made was to use the 100% grayscale control instead of the White Color control at 100% stimulus (if you pre-calibrate here neither would be used anyway) and to run the routine from bottom-to-top, rather than from top-to-bottom.

I ran two grayscale/gamma and 8-point calibrations on my Pioneer plasma (no 100% pre-calibration). The first is with the Pioneer set to Movie mode, so small adjustments were required. The second is using the Standard mode where large adjustments were required.

Here are the results, unedited.

CalibrationSummaryDetailed-Movie.pdf 283k .pdf file

CalibrationSummaryDetailed-Standard.pdf 306k .pdf file

The Movie mode calibration using a D3 took 6 minutes. The Standard Mode calibration took 9 minutes. Obviously, a 125-point calibration will take longer, in the 20-25 minute range.

Tom,   What about a display w/o a CMS, such as the SonyVW1000ES?    What pre-calibration is possible (or necessary)?

This isn't about the CMS. It is about the 100% grayscale point only. Use the Sony's own RGB grayscale controls and CP's White Balance module to calibrate white at 100% before running auto-cal.
post #4067 of 5348

An unrelated question I would appreciate help with:    when I try to print something from the Forum nowadays, the printing is very light, barely readable.   It didn't used to be this way.   Is there something I'm missing on a 'preference' or a print facility?

post #4068 of 5348
Good to see 0% readings added. This does however make AVSHD rather less convenient due to there being no 0 IRE pattern in the ChromaPure sub-section.
I wonder if alluringreality would consider authoring a new disc to accommodate this?

I tried a few times yesterday with the 2.4.0 but the results were bad and odd. Today I tried with 2.4.1 and followed the instructions, worked perfectly. Image looks great!


Because of my lack of experience I cannot say if the small windows are what made the difference, but to me it seems using them made my vt50eu a lot better. Clearer, brighter image.

Worth the wait!

small windows - 1% or 2% ?

Actually, it has nothing to do with window size. It was just changing the 100% calibration method and going from top-down to bottom-up. The 100% method change alone probably would have done the trick, but changing the order certainly didn't hurt.

Remember, until we release the full version of 2.4.1, all Lumagen 8-point calibrations must use 100% stimulus patterns.

Whatever the Lumagen uses. I haven't measured them. They are very small, I think smaller than they need to be. We use 5% small windows in the AccuPel and Duo.

Lumagen's Window Pattern Size:

Medium Windows size: 11.11%

Small Windows size: 1.56%

Tom,  I apologize if this is too display specific, but I don't see any RGS (gain/offset) controls on my Sony1000.    Are these in the service menu?

It's been months since I did a cal, and using 2.4.1 tonight - didn't there use to be an option for 5 or 10% greyscale in the advanced auto cal window? It's not there in 2.41... is it somewhere else now, or does chrompaure use whatever is set in the Lumgaen when you start?

Eh, I found it in the settings...sorry

The first cal was all whacked out with posterized colors, I guess because the Lumagen was set to 21 point and Chromapure was set to 10% greyscale...running another cal now...

Color Temp, Custom Menu. Start with Custom 3.
