ISF Day vs ISF Night

Hi,

I had some fun this WE making an ISF "Day" calibration vs ISF "Night" with my new i1 Display Pro.

I follow Tom's good advice to re-calibrate (without a LUT) my non linear KURO 9G to 75%.Rec709.

It's interesting to note that the picture looks pretty much the same (i prefer ISF "Night") while there's a huge difference at 100% (166 cd/m2 and 127 cd/m2).

I didn't expect to achieve such great results (for me) for the ColorChecker (especially Skin Tones) with the ISF "Night" calibration !!

I made my own ColorChecker Report with the data as i didn't succeed in running one with ChromaPure and Excel 2013 (i did follow all CP support's page and tried a clean install but without success - Anyway, it doesn't matter as version 3 is coming ))) and as i had a lot of fun with making graphs & stats !!

Have a nice day,

Pat

Your personalized color checker graphs are really nice.
Did you replaced the existing files from C:\Program Files (x86)\Display Calibrations LLC\ChromaPure\Reports,with the new one from ChromaPure support page,without any succes?

Hey, THANK YOU Maximus !

Yes, of course... First, i resolved the security issue for Windows 8.1 and as i'm the administrator, i checked that I have all permissions, full control for ChromaPure.
Then i replaced the report by the updated one, as described... and yes, without success... I mean the report is opening normally but data are not the ones measured during the calibration and are very weird especially for the pre calibration.

I also changed the system preferences to use periods for decimal points and commas for list separators.

Finally, i followed the procedure for a clean re-install...

Maybe i'll make another try... but it doesn't matter, now, i know how to make a graph

Hi Pat, I looked to your ControlCAL Settings. Take a look of some Brightness Patterns or others from the Color Reproduction session of my disk to check your Near Black, to see if the shades are neutral, the -5 of Red Low can produce greenish shade to your shadow details.

v. 3 Update

I had hoped to get ChromaPure 3 out by the end of this month. I am now pretty sure that this is not going to happen. I think that our release date is going to slip 4-6 weeks.

We have all but finished the changes to the UI the main program feature enhancements. I still have to do testing, write the documentation, and we have to rework reporting, which is undergoing a fairly substantial upgrade.

I now expect release during the late April-early May window. I want to repeat that if some treasured feature is not in v. 3, please don't freak out. ChromaPure 3 simply offers a new platform on which we will continue to build. If you look at the improvements that appeared between 2.0 and 2.5.7, you get some idea of what I am talking about. I am already planning 3.1.

That's the best information I have now.

As this announcement disappoints me I'm glad you are going for a quality release instead of releasing a product that's just not ready as so many companies do these days. I deal with too much software in my business that is released to the public to get the $$ in there hands even though they know its not ready.


I would prefer to wait for a finished product then spend time chasing my tail only to have to wait for V3.1 with a long list of bug fixes

Hello,

So... i checked that last night.

Your patterns are so nice.
I have also DVE Essentials and Spears&Munsil (last edition) BDs, and i prefer yours as it's more easy to navigate.

My poor eyes don't see fortunately much green on near Black... and everything looks quite good
It's certainly not perfect, but i think i can't do better... next step is LUT !

Hey Tom,
Just don't release it until you are satisfied with the results. If you have any hesitation don't release it, cause you know it isn't right. It's sound s like you are going for a quality product in Chromapure 3, all you have to do is make sure it is.
I for one can wait for quality.

I feel like I am having trouble with my "Test Gamut".
When I run it (after calibrating) I get about 85% as poor de values. However, when I use the color checker all the de values are under 2 and some are under 1.
Am I doing something wrong?


Thanks.

Tom,
Sent you the reports via email as I couldn't figure out how to do it on this PIA new setup.


Thanks

Newbie to Calibration Seeking Your Wisdom

Hi, all.

I am a long time HT enthusiast and a newbie calibrator, and I need your help. I have a new Sony 350ES and a Screen Innovations Maestro White acoustically transparent scope screen. Here's the problem.

I am setting my White Balance through the projector's service menu, and getting great results, and setting the Color Management through the projector's CMS, and getting great results. Yet, when I run the Post-Calibration Color Gamut Test, I get lousy results.

It's as if my "Chromaticity" is perfect according to one tool, but my Chromaticity is imperfect according to the other and my "Luminance" is way off. I don't know how to fix the Luminance, nor even which Chromapure tool to use to address that. I also don't get why the Chromaticity is not the same between the two tools.

Sorry if this is elementary to the veterans here, but I could really use a hand.

The two images attached were obtained one right after the other, without changing any setting or moving the sensor. The first is from the "Color Management" tool and the second is from the "Post-Calibration Color Gamut" tool.

Look forward to benefiting from your collective wisdom.

P.S. I am calibrating using Rec. 709 at 75%, based on Tom's recommendation, but I also don't fully understand the implications of that. I assume it means my test patterns are also 75%, but I really don't fully grasp what I'm doing.

Yes.

I should have responded to my own post as I received confirmation from another source. Thanks.

Is there a specific add on needed to use this pattern generator? The only options i have are the built-in and the dvdo duo. I do not have the option for the dvdo avlab-tpg. Am i missing something?

Thanks

It is supported by ChromaPure Professional and ChromaPure Plus. If you have ChromaPure Standard the only external generators supported are the DVDO Duo and Lumagen Radiance.

Tom, is a manual sync setting of 60 normal for the CR-250 spectro? Just asking, because the auto-sync on the CR-100 usually reads 240.10.

Yes, it is. Often the CR-100's sync detection reads a multiple of 60, which is harmless.
