Hi Tom and Jim, congratulations for your staff's job. Thanks.
In the new 5x5x5 fantastic cms you have entered these values for the saturation:
16 71 126 180 235 .

According to our calculations if you want obtain 25 % for one step, the values should be:

16 70 125 180 235
(i attach the table in this: http://www.convergent-av.co.uk/forum/index.php?t=msg&th=2448&prevloaded=1&rid=883&S=aee440ff4408bc95b29d413d31e75548&start=90 )
Why do you choose them?
Where we err?

It calibrates whatever is the active configuration when you start the process.

I am not sure that I understand your question. If what you want are the RGB triplets that give you 25% steps of saturation, they are (approximately):



The reason that this is approximate is that the Lumagen system provides color points defined by the 5x5x5 matrix, not by levels of saturation, so once you consider gamma the distance between the fully saturated color and the white point are not exactly in 25% increments.

There is new Lumagen firmware available.

http://www.lumagen.com/docs/radiance_mini091112.zip

I strongly recommend that all users download and install this.

I guess I am missing something, if you have to reset all the CMS memories to default before you start, doesn't that effectively defeat the purpose of having different CMS slots?

Only the active CMS memory will be set to default.

Ordered a Radiance XS today from Tom along with the Advanced Auto-cal. Should have it in a week or so. Looking forward to any first hand experience or tips with using the 3D LUT stuff and ChromaPure. Used to working with a DUO and my displays CMS. Are the Radiance manuals floating around on the web somewhere so I can get a head start on familiarizing myself with the beast?

Start from there. wink.gif

Tom,

I've been looking at the hardware requirements between calman and chromapure. Calman recommends a 2ghz dual core processor with 4 gb ram.

On the chromapure webpage, I see under requirements, 2 mb of ram(must have meant 2 gig) for vista or windows 7. No mention of processor. What do you recommend if someone is wanting to use chromapure with and without the 125 point calibration????

I'm running a dual 1.6 ghz processor with 2 gig of ram and concerned if it's enough.

Jim, FWIW Im using A Dedicated low-end notebook/Compaq Presario with a Celeron 2ghz single core & 3g ram With Vista, running Calman Ultimate edition with know apparent problems, inc 5x5x5 lut cal...

All DEs are less than 2 at each level with the exception of red at 25%. Doing 25 and 50% first makes 75 and 100% easier. Their DEs are all less than 1 with luminance variation +/- 2%. Checking other % points shows tracking at 35, 65, and 85% to be consistent with calibrated points DEs. Exception is yellow which moves a bit and might have grown to a +2 DE at 65%. Cyan is no longer a problem at any measured point. IMO calibration with a Radiance and the new 555 firmware fixes the Elite color issues.

If you are content to do this manually, that's fine. All auto-cal will do is calibrate all of the 124 points for you much faster than you could manually. However, with patience, a Lumagen, and the new firmware you can certainly do this yourself without any automated process.

Tom: Thanks. Setting on the fence since the upgrade to auto cal plus a new meter will cost me ~ $600 per what's posted on your site. I will continue to sit for a while until any bugs appear to be worked out in both Chromapure and the Radiance. Interesting observation is that simply installing the 555 firmware and turning 125 point on in an existing 8 point CMS seems to have greatly reduced the cyan problem without a new calibration. Never saw that many shades of blue on the Elite before! Never knew teal was used so much in commercials.

just purchased cp so am a first time user. hopefully it lives up to me expectation. have autocal and advanced for my lumagen

I am sure that's enough. Let me do some testing with Advanced auto-cal and I'll update the system requirements.

within the auto calibration section there is a brightness and contrast pattern. when doing the contrast it takes to plus 18 for one of the white bands to disappear but white looks clipped when it does it and i quickly run out of red. i have not seen a jvc 350 projector anywhere with a contrast setting away from zero

I use to have my X3 (2 years, 1000H) contrast set at -12.
This is to avoid some discrepansy at the top of the luminance (above 70 IRE) and get more horizontal colors gamma in this area.

Thanks, so by doing this does the white band disappears as per the instructions?

No, with the JVC the contrast is useless for this operation, you need to use the gamma for that.

Hi Tom,

i received my licence from Ricky for i1pro-spyder4-DTP94 but after choosing the DTP94 and apply the mode (i.e. lcd,crt) many windows are popping up to take a dark reading
but after 10 seconds there are so many popups CP is crashing and there is nothing i could do.

i tried install CP 2.1 and 2.3 but the problem keeps comming back.

I have ask Ricky by mail and he has the same problem with his DTP94 so this could be a bug report from us.

Thanks,

Danny

I have used a 6 year old DPT94 with CP many times and have never experienced those issues..

Most likely the problem is due to the current design/construction of the meter.
Mine was purchased from Monacosys around 6 years ago, the meter was made by Xrite.

Mine is Monaco Optix XR made by x-rite.

I think the time for taking a dark measure has to be reset in licence file or CP software.
post #2905 of 5345
Is it better to just adjust the displays RBG to a flat 100% white balance before commencing with Chromapure over 30% & 80% adjustments?

I ask as I have successfully calibrated my JVC 350 with a D3 meter having adjusted the white balance at 30%/80% using the JVC RGB Gain's and offset's 'I never use positive value's on the offsets' But I never seem to be able to get good results just adjusting at 100%?

I am missing out by not being able to?
post #2906 of 5345
The best way to calibrate a JVC-projector is the following:

1. Adjust contrast / brightness
2. Calibrate 100 IRE ONLY with the GAIN controlllers of the JVC - DON'T touch the offset controllers !
3. Calibrate 5-95 IRE (RGB balance and gamma) with the gamma equalizer

But be careful: it's a little bit "tricky" to use the gamma equalizer of the HD350, but it's possible,

I have updated our system requirements.
1.5 GHz CPU (Dual Core will run faster, but it is not a requirement)
2GB RAM XP, 4GB RAM Windows 7

The main variable with the speed of 125-point is dE target and the meter itself. I would strongly recommend the Display 3 PRO, Hubble, or K-10. Also, dE targets below 1.5 will substantially increase the time required to complete the process without any visible increase in performance.

Those running CP on a Mac with Boot Camp, Parallels, or Fusion are reporting 125-point times about double what I am seeing, so there is obviously some bottleneck there I don't really understand.

What's ChromaPure dark reading timer for X-Rite Hubble meter? Is Hubble able to perform a full 125 LUT calibration without problems?

We don't use a timer, and leave that up to the user. Sure, why not?

I saw that X-Rite Hubble/OTC-1000 has Dark offset timer for every 10 minutes using CalMAN Software.
