Is it possible to set the APL % and window size % while using APLs during autocal with a Lumagen? If not, what is the default spec on the APL in autocal.
You can set the values that are available in the Lumagen setup window.
Fields
Windows (10%)
Medium Windows (5%)
Small Windows (2%)
APL Windows (Medium window, 25% APL)

Ok, thanks. I was just wondering if there was a way I could customize the APL % and window size while using autocal.

Hello,Tom
What it means "reset the current settings" from auto-cal?which settings will reset?

Thanks

When i configure my chromapure with auto-cal on the last page where i have three box to check one of them(color-matrix,reset the Lumagen to default, and reset the current settings) if i remember correctly.

Sorry i am not at my home to say for sure.

ColorChecker Reports

I have posted complete instructions for fixing the ColorChecker Excel reports on our Support page.

The upshot is that for XP and Win7 users, all that was required was an update to the Excel files, which are provided on our Support page.
For Win8 users it is also necessary to make some changes to avoid Win8 throwing a security violation. In fact, you can't even update the Excel reports until you do this because by default Windows 8 prevents the user from making changes to the necessary folder.

1. Right-click the ChromaPure icon on your desktop, and select Properties.
2. Click the Security tab.
3. Next to "To change Permissions, click Edit" click the Edit button.
4. Select your Windows name.
5. In the Allow column, select "Full Control".
6. Click Apply.

Now you can update the Excel files.

The first setting resets the color matrix to default, but leaves gamma/grayscale alone. You must adjust them manually.
The second setting resets both the color matrix and gamma/grayscale to default.
The third setting resets the Lumagen (and all settings) to the factory default.

I recommend the third reset option.

No. They should test their software. No laptop is being sold with Win7 for the past year and Excel 2010 cant be purchased either.
The software is compatible with Windows 8. It is just that it introduced a lot of extra security features that makes certain tasks more difficult. I haven't tested the reports on Excel 2013, but it uses the same file format as 2007/2010, so there shouldn't be any problem.

Can you elaborate on why you might recommend that option? Suppose I want to have one Lumagen memory be a 2.2 gamma and another be BT.1886. Surely I want to use the advanced autocal for both. Resetting the entire box to factory default is pretty incompatible with that.... What are the other autocal requirements that need resetting?

I understand, and this is why we provide the first two options.

I have just found that clearing everything out and starting fresh provides the most consistent results. I can't provide any scientific explanation for this. It is just my experience. In particular, I would not attempt to do more than one auto-cal session without resetting to factory default. If you need to do more than one session back-to-back without resetting to factory defaults, for whatever reason, then I would close ChromaPure and restart between sessions.

Hi Tom, I have a different query which you may not be able to answer, but anyway;
Using Lumagen XS up scaling to 1080p output
Set 1080i source. On CP I set up for rec709. Adjust White Balance on TV, do Autocal.
Come out of CP, go back in
Set 576i source. Setup up for EBU.
Check White Balance and it has changed.

Would you expect this change? Presumably I can't adjust the tv again as this would mess up my previous rec709 calibration. any thoughts? Thanks. Chris

Not based on the information here. In particular, I'd like to know what, exactly "changed" means. Changed a little, a lot, throughout the whole grayscale, only part? A pair of calibration reports would help.

Not at all for the calibration of an external display. You might want to calibrate the white balance of the laptop, just because it looks better. You can use CP's Built-in test patterns and the video card's color temp adjustments for this.

Hi tom, did not think to check greyscale, just the White balance. The White balance is not different by much, say red by a couple of clicks on the TV control, it's nothing major, just a bit surprised that's all. Thanks anyway. Chris

I have a Lumagen mini rather than an XS, but I see the same thing with greyscale and advanced autocal. This is from an earlier version of Chromapure rather than the new faster autocal so your mileage may vary, but I do the greyscale on the Lumagen by hand and then run autocal using the setting that leaves greyscale alone. Post autocal my greyscale is noticeably worse than before.

I traded email with Jim Peterson at Lumagen and his comment was that the 5x5x5 matrix has points on the grey vector and so can affect greyscale. His recommendation was to go back and touch up greyscale if necessary after the autocal. That's what I do currently but it seems to me that if the 5x5x5 autocal affects greyscale then greyscale affects the autocal so I'm not really sure where I end up deltaE-wise across the gamut.

Of course, crosstalk like that between adjustments is the name of the game for calibration, so I tried "adjust grayscale, run advanced autocal, adjust grayscale, run advanced autocal again" but it was a lot of work and it wasn't apparent that it was converging so I reset to factory and contented myself with grayscale, autocal, grayscale.

All of the auto-cal modes: 5^3, 9^3, and 17^3 have adjustment points that overlap the grayscale, 4 points, 8 points, and 16 points. If you haven't used the faster method that we implemented a few releases ago, then you really need to upgrade. It uses a completely different method. It is not only faster, but it provides a much more precise method of adjustment because it is mathematical, rather than reiterative (that's why it is faster). What I see is that if I did grayscale first, then when the matrix adjustments get to the grayscale points it makes virtually no change because it is pre-adjusted.

Some post-matrix calibration grayscale adjustment is almost inevitable at the low end. The dE method we use--unlike other vendors--provides the maximum sensitivity at low light levels so getting a good white balance at 20% and below may require a little TLC. If you limit the post-calibration adjustments to that then it won't have any meaningful impact on the color calibration.

BTW, I want to encourage everyone to offer quantitative data in these posts as often as possible--a calibration report is easy to post. For example, it is hard to know what "noticeably worse" means. Is it measurably worse (by how much?) or visibly worse? It is always best to have hard numbers.

Tom,

It appears, to me anyway, that even after selecting Reset Color Calibration Settings Only and not selecting Grayscale/Gamma, 2.5.5 still calibrates grayscale, see data below.

I have been getting a lot of this lately, and I don't know why. You have a bad installation. Here are the instructions for a clean installation.

1. Uninstall CP.
2. Delete this file
C:\ProgramData\Display Calibrations LLC\ChromaPure\2\ChromaPure.config
(If you don't see the ProgramData folder, that's because it is hidden. To expose it, Control Panel, Folder Options, View, check "Show hidden files, folders, and drives". Then click OK. Now it will be visible.)
3. Repair Microsoft .Net Framework (Control Panel, Programs and Features, double-click Microsoft .Net Framework, and select the Repair option).
In Windows 8 you need to download the repair tool
http://www.chromapure.com/distribute...RepairTool.exe
A reboot may be required.
4. Reinstall CP.
5. If you are using a signal generator, you will have to set it up again in CP from scratch (use a Com port of 4 or higher). Click Options, Signal Generator.

I want to make sure that readers understand that the issue you encountered has nothing to do with the reset options. What you encountered is a grayscale calibration when none was requested.

Here's what you should see with a Lumagen matrix calibration only (no grayscale/gamma) with the reset grayscale/gamma and color settings checked. This reads in reverse with the last event being my cancelling the session. BTW, thanks for posting data.

It now works as advertised. I'll keep the reinstall procedure in my hip pocket in case I have any future problems. On the plus side my measurements at lower IREs on my F8500 are stable within a few percent. By stable I mean they don't jump around 10-15% when measured continuously. And my skin tones are no longer orange/red in color. It looks fantastic now.

Let me recommend some third-party software that is really useful for keeping a Windows installation running well.

https://www.piriform.com/ccleaner/download

I use this and I never have these problems with bad installations that have gotten more common as the program has gotten bigger and more complex.

Ahh yes, CCleaner. I use to use that back in my Windows days. Thanks for the suggestion.

I do have a Lumagen question. As you may have noticed in the data I posted, the display is quite bright. Is it practical to lower peak luminance using the greyscale controls within the Lumagen? I'd rather do that than have different TV settings for day/night.
