CalMan 5 Release Notes and Discussion - Page 29

Looking at that crash log it looks like you're running 1072 and that specific crash is one we fixed in the 1087 build, the current build is 5.1.0.1092 http://www.spectracal.com/forum/viewtopic.php?f=101&t=4552

I think you'll find that using the latest build resolves your issue and gives great results.

Ok some good news! I downloaded 1087 build and got through an entire autocal thank you. Best 100% auto cal result I have had so far.

The only issue I continue encounter is a socket error because I tend to loose connectivity to my VT50 for some reason during auto cal . I am connecting via IP wirelessly. I have a very strong signal ( am right next to router) not any interference that I am aware of. Any suggestions?

This may be a little OT for this thread, but I'm having trouble with shadow detail. The gamma ramp looks fine as far as it goes, but I loose detail somewhere under 5% IRE. I manually play with the Lumagen at the 2.5% point (thanks for letting me know I could do this) and I get detail, but other parts look weird... too bright. So what I think I want is some test pattern that shows 1%, 2%, 3%, 4% up to, say, 10% bars so I can play with a combination of the JVC's gamma controls for the 10% point, freeing up the Lumagen's 10% control to move down somewhere near 5% and then use the lowest Lumagen point at 2.5% level or so. Does anyone know of a source of a test pattern like that? Or, is this a fool's errand?

5% is often about where the black level hits the gamma curve.

.05^2.2 = 0.00137 Yn, So if you have 100 cd/m output, then 5% target is 0.1
.02^2.2 = 0.00018 Yn. So target output is 0.02

So for most TV's somewhere between 2% and 5% you run into the black level.

If you want good shadow detail either try turning on "use measured black level" or try using the BT.1886 formula (which does use measured black level).

I'll try the "measured black level" option. As I recall, the low level boost of BT.1886 extends up too far for my liking. But that was only from looking at the curve. Maybe I should actually try it! Thanks.

BT.1886 is recommended for displays that don't have enough contrast ratio to do a proper 2.4 gamma. My projector measures (with a C6 from Spectracal) at 24k:1. I'd think that would be plenty. As I said before, the 5% pattern displays fine. It just rolls off to quickly from there. But I'll try it and see.

OK... so here's a question I always feel dumb asking... "How do you do it??" Turn "use measured black level" on or off, that is.

I've reviewed the forums, CalMAN itself and CalMAN's documentation. While I can find entries that tell me I can change that option, there's nothing that tells me how.

I think if you choose this option you would be told to measure 0 IRE and that´s the black level.

Regarding test patterns. Go into the Radiance adjustable test patterns and select contrast, push the number 4 on remote and try 3 of 11. Hope it works.

Yes, I get that. But my question is, where do you choose this option? I can't find it and SpectraCal's search option doesn't present anything about it. Again, I feel like a dope. Thanks in advance.

Cool. I'll try that. I'm exploring different paths with this.

I gotta say, doing a search in CalMAN's help for "use measured black level" and actually finding a topic with that title only to see they say "work in progress" is pretty disappointing. Likewise I find nothing on their forums about it. I really appreciate having y'all around to 'splain things to me!

It's here under advanced workflow options, under the gear icon.

Cool. Thank you!

Just got to see my results from last night's calibration with Beta 1072 - unbelievable the results I'm getting!
Have also found by calibrating the Service Menu White Balances Cool, Medium and Warm, all to Warm settings, has greatly stabilized the TV, and again helped with the improved appearance. Have also found doing the SM WB RGB Cuts, it was better to set Calman to 20IRE instead of 30. Faster and more stable results, then only the odd click after for 30 to fall into line. The 2/10 Point Setting is now left on 2 Point - 2 Point for me to calibrate, and 10 Point for either the XE or Duo.
Will tweek last night's results with the newly downloaded Beta 1092. Will be looking to see if the 125 Point time results are improved or not.
Thanks to the programers at Spectracal from getting us out from the old, dingy, dirty Yellow final results - love it! Keep up the good work, and I'll never have to buy another TV again! Well - until OLED, Passive 3D, and 4K comes down to my price range!

First results are in: program pulls in about 25% faster. (It appears some of the settings I like to use, are now being retained from my last calibration, others are going back to defaults. Now if we can only remember all of them, it would save some setup time, and trying to remember them all!)
Grayscale was previously having to be redone 4 to 5 times before I was mostly happy with the results. Now, was doing great, and it looked like only 1 calibration had to be done, and I'd be really happy with the results! BUT, got to 10IRE, and it clicked twice, and were on the older versions it would be almost perfect, this time, less than perfect. It appears that either Calman or the Radiance, clicked back to the underlying Program, just when the Meter clicked it's last click, throwing off the calibration. A second sweep corrected 10IRE, and tightened up all the other IREs, and in a lot closer tolerance. I was using 0.40 for the target. Now getting 0.10, with overall average of 0.30. Better then my manually calibrated 0.36. No more weird looking wild swings just on the last click!
Looks like either something needs to be done to stop the whatever that's switching back to the underlying programming, or some kind of delay be implemented after the very last click.
Currently doing the 125 Point. Will report back the results tomorrow.

125 Point Calibration was done in 28 minutes, instead of the usual 30 to 35 minutes. Grayscale had very little change.

iScan Duo AutoCal on the downstairs LG - took a lot longer, with a lot more sampling, and not near the results from the XE and the 125 Point.

Anybody care to chime in?

It doesn't NEED the dark cals, they are just there to improve low end accuracy.

Most of the darkest readings in a radiance AutoCal happen early in the process. We have seen internally, that running a radiance Cube AutoCal with an i1Pro works very well. Just make sure to re-init the meter after grayscale and before the Cube.

I have Calman 5.04 Control. With "Color Checker" I can only check gray scale, not color. Is that a limitation of the Control version?

I'm using a DVDO Duo as the pattern generator. Both in the quick analysis and advanced workflows. I go to color checker, all there is is a grayscale. How am I supposed to get to a color gamut checker? I tried running a series; it just reads the grayscale and then quits. I mean, I know how to check the 6 primary and secondary colors. But I thought the Color Checker tool checked a whole range of colors?

Does colorchecker view show all the different colours on the bottom?

No, just the grayscale.

Assume you have selected Colorchecker in left hand menu?
If so and only grayscale buttons showing on bottom:

Try pressing top right third from right button to show 'Workflow and Application Panel'.

Active Layout points should be 'colorchecker', if not select it from drop down menu.

This should show colorchecker buttons on bottom.

At least thats how it works in Enthusiast version.

All that is done, no color.

Post a screenshot please of what your are seeing.

Here you go... And BTW, Thanks!

Hold tight till Sotti can get you sorted. What I think the issue is can't be fixed without having access to advanced mode. As you have the Control version of CalMAN that's not available to you. Or give SpectralCal a call and ask about this.

Re: i1Pro dark reading requirements - I did some testing a while back and it turns out that the only drifting was the display itsef, not the meter. Read this and maybe do a similar test to see if your meter responds similarly.

http://www.avsforum.com/t/1323457/i1pro-dark-readings-i-dont-get-it

you can go longer than 12 min on the i1Pro for the dark cal.. do it at the beginning of your session and go.. some like to check it every 15-20 minutes.. but you can even go longer. you're fine with the radiance's lut cal

it really doesn't take long to do it anyways.. not sure what the rush is for home users.. Pros still use this meter and they are not complaining or rushing out for a i1Pro2

when using the meter in contact mode on a flat-panel display, is it acceptable to just turn off the display and do a dark reading? or will some light still get in and mess it up?

how about a CD case (optionally with a little black felt or rubber patch)... even in contact mode I use our extension bar with a tripod, can simply tilt or rotate it back a bit and use the case.

Or perhaps you can pay the money for their Beamer #A-H/EOB (expensive though) which has a shutter to do this.. buzz has one and mentioned the shutter if I remember correctly. I don't have the beamer holder.


Our extension bar:
