CalMan 5 Release Notes and Discussion - Page 32

Yah, this makes some sense. If we think in terms of the meter being at even the slightest angle when it is that close to the screen, this is probably 3x the angle we are viewing the screen from seating position. So somehow we need to simulate the calibration to approximate how our eyes are seeing the angle and brightness/color changes. Up to this point, I just adjust the final calibration by eye after the fact, but it would be nice to use the meter correctly in this case.

I will try a few things and see if I can get anywhere, maybe moving the meter far back as to have a lower angle of incidence or grazing angle to avoid the shadow, calibrating from the lens, etc... I have a white wall behind the screen, could try calibrating against that, or getting out my tripod screen as well.

You are right though, the problem is also that is hard to tell if the meter is reading a white shadow, I can tell when it's reading a dark shadow but sometimes the HP screen can reflect a white shadow from an object (hard to explain).

I love my HP screen for added 3D brightness, but I can't say it's the easiest to calibrate with

I had/have a dalite hp I had set my Klein K-10 at my viewing position, at my eye level (where I sit is the best location - sorry family and guests lol ) aimed just below center of the screen (which is my eye horizontal level for my particular setup)..

I do know calibrators who use i1Pros and have done it this way as well.

I actually prefer to meter at my viewing position for my fp setups

I didn't even know you could do that! How do you know how much of the screen that's not illuminated by the test pattern the meter can see from that distance?

That is pretty funny. If someone were to use a Panny 4000/7000/8000 it has a split-screen calibration mode, theoretically someone could get some neutral white material, put it over the HP, then do split-screen calibrations until the meter reads some calculated offset near the middle about the same, then use that as an offset (though where each person sits will still affect it, but that might be a good start).

Even without a split-screen calibration technique, I think I can come up with an offset method that is ballpark between a neutral white material placed near the center of HP, and take center reading of HP, then repeat at seating angle, and take the lens reading itself all combined into one master offset.

the thing with the dalite hp is more on the vertical angle, in fact, the same angle with a ceiling mount vs lower mount for the projector will be different, preference is to ceiling mount.. and viewer seating height and viewer height should be taken in account to (again sorry my shorty family and friends if I happen to have the hp up).

use full fields

obviously, your meter should have a viewfinder w/optics (Photo Research, Konica Minolta), targeting leds/laser (Klein, Hubble?) or you can calc the fov. Should not be a problem at >=100" - you don't want to target/include outside screen either

Us Seniors are supposed to learn at least one New thing a day:

For today: when using and calibrating with the Radiance VQs, DON'T Calibrate the THX Mode. So, tonight, calibrated the Game Mode as I was told to do. Grayscale came in flatter, and 125 Point Lower. Then someone told me, because Game Mode on my set turns Off the Backlight. Calibrate the Expert (ISF) Mode instead. Confusing?

Game Mode - MILKY BLACKS - Moved over to the Expert ISF Mode instead.

Calman has released a new Beta 5.1 1100.

Just ran a LUT cube and it seems to be stable.

Good to know. Thanks for the note. I just downloaded and will be trying it out today. I had pretty good autocal results with the last beta version--hoping 5.1.1100 will be even better. Since then, have been viewing Michael Chen's video calibration series hoping to sharpen my skills.

Hello

Thanks to spectracal.

I tried the new beta 1100 and it is very very good. The balance between autocal before 3D LUT and autocal after is perfect for all of the parameters (with a Lumagen Radiance) !

Gamma autocal is slower but better (20 minutes instead of 10 mns)

3D LUT autocal is as fast as before.

Regards

Downloading and will try tonight on my Expert ISF Mode.

Note for those wanting a Radiance, and a Darbee inclusion, due to the delay in implementing, an External Darbee Radiance Special package can be purchased.
Edited by p5browne - 2/2/13 at 9:45am

I don't understand why you you keep posting "delay in implementing". Darbee processing was never planned for the current Radiance line.

He says "for those wanting a Radiance" meaning he's addressing those who don't have a Radiance yet. So he's discussing a delay in implementation of a new product that will include the Darbee technology. Clearly he's not discussing the "current" line of products.

Thanks for the clarification. I guess I missed Lumagen's announcement that the new VPs were due to be released and more importantly that the release date has been delayed. Any link to that info would be appreciated.

Hmmm... it might have been more of a Darbee announcement. I don't remember exactly, but I think that's where I read about the licensing deal with Lumagen. But then it might have been clarified about it being a new product on the Lumagen site. There was some discussion of there not being enough gates on the current Lumagen lineup. Sorry... I didn't save the links.

I've seen those announcements and all that I have read made no mention of when the new VPs would be available. I would assume there is something other than these press releases and the forum posts that have been made by Lumagen and Darbee regarding this partnership that references this delay of implementation in the new product line.

This link mentions early 2013 and quotes Jim Peterson:

http://www.marketwire.com/press-release/darbeevision-licenses-hdmi-video-processor-design-to-lumagen-nasdaq-ueic-1742519.htm

Yeah... I don't know about delays. I was just responding to what I though was a misinterpretation of what p5browne was saying. I already have a Lumagen and I'm not interested in 3D so I'll prolly get the new non-3D Darblette when it becomes available. No rush...

Check the www.curtpalme.com Website for pricing on the Combos.
It's great to announce the Darbee Lumagen relationship, quite another to come up with the deign, building, testing within a short time frame. So, since the cat was out of the bag, rather then clients having to wait for the new products, lower the price to clear inventory, and throw in the External Darbee as an incentive for those sitting on the fence. Look at the % OFF regular pricing - even better than Black Friday's and Boxing Day's pricing! Why go Mini, when for a few hundred more, you can go top of the line! (With More Inputs!) And now with Calman 5.1 now getting to do a great bang up job of the 125 Point - now your TV or Projector, can shine in all it's glory!

I havent been able to get very far with the new beta 1100 today. I seem to lose display connection more frequently than normal. When this happens I get an error code 59 " Display Connection Timed Out" and I have to stop the calibration. Disconnect the Display and then go through the Display connection process all over again. This problem is not unique to this new beta version. I've experienced the same with all version of Calman that I have used. Seems just more frequent today than normal. See screen shot below.

Screen Shot 2013-02-02 at 9.13.09 PM.png 188k .png file

Any idea what is causing my display to disconnect so often and what I can do about it?

Panasonic VT50
C3
DPG2000
Calman 5 Control 5.1.1100 ( Windows 7 Ultimate)

VT50 connnected wirelessly to in-room wireless router ( Linksys e4200 v2)
Mac Air connected wirelessly
C3 USB directly to the Mac
DPG2000 IR USB directly to the Mac

Wireless connections are subject to all kinds of electronic distruption: ie Cell Phones, microwave ovens, etc. For any kind of calibration, I would definitely NOT use any kind of Wireless Connection.

Wow, what happened? Downloaded the new Beta and thought I'd had a problem download! Program's installer file is about 1/3 Less in size!
Big change re my Service Menu White Balance RGB Cuts calibrations: all the Cuts dropped about 10 Clicks each! RGB Gains stayed about the same.
AutoCal Grayscale - only 1 Pass needed. 10IRE I thought was going to fail since the underlying program popped up right at the end. But came out OK by a fraction of a second between the last click, and the programming popping up. Previously, it was a fraction of a second the other way, and ended with a 10IRE calibration error, forced me to do a second calibration, wherein 10IRE was OK.
Upper end of the IREs, now sample a lot faster, and more accurately.
Currently doing the 125 Point calibration as I type this note out.
Noticed after doing the Optimizing before getting into the AutoCal calibrations, the overall White checks now came in Lower then previous Beta Versions.

125 Point Calibration took about 10 Minutes longer, but this was made up by the Grayscale being Faster!
125 Point had a problem with 2 of the colours, but after turning my LG Off, then back On, Grayscale came in Flatter to Reference, and now the 125 Point had no issues, and again, was Flatter to Reference. Still took 38 Minutes, but 141 Samples the Second time, versus 148 Samples the First.

Agreed. I had the same problem when I was using ControlCAL with my previously owned Sharp over WiFi. Ended up using a cable from my laptop directly into the TV, configuring manual IP addresses for each interface, to get around the issue.

Worked muy bueno after that.

All the workflow files are now compressed when downloaded instead of requiring a save after the download.

Thank you. All cabled-up ( no wireless connections) and going through it again. 100% autocal with Enthusiast this time ( Beta 5.1.1100)

Update: First time ever I didn't experience a display disconnect during full auto cal. Thanks again for the tip.

I am trying to Autocal my Panasonic VT50 tv, and have the Control license for Calman5. According to the Spectracal site, and an email received from them, you use the patterns within the VT50 to do the calibration. I am using the HT Advanced menu, and I have no trouble connecting with the TV via wireless, and can get as far as seeing the ISF Day box at the bottom of the TV. I can change various settings in the box by going to the DDC panel, so I know the TV and Calman are communicating.
Question--How do you access the patterns in the television, which is what Spectracal is saying you need to do?
Anyone here have any insight as to how you access the Panny patterns within the TV?

Thanks for any help,
Wayne

ruegway: I use a DPG2000 or Digital Pattern Generator ( from SpectralCal) . However, you can also use your Blu-ray player with AVS HD ITU-R BT.709 disk to generate the patterns. Check this url ( for free downloads etc.)

I think he says that the Patterns are Within the Panasonic already. Not having to use an External Pattern Source.

Sounds like game mode was operating at 0-255 instead of 16-235... if there's a 16-235 option available for Game mode, it still might be the best option.

And re. "turning the backlight off"... I don't think that's what you mean... the panel would be black all the time. Maybe you mean that it turns auto-dimming off?

On my LGs, using Game Mode, you have no Backlight, and no Option to turn it On or Off. Leads to Milky Blacks. Now Calibrating with Expert Mode that has Backlight.
Apparently, there's some kind of Auto Colour Mode in THX that affects the Lumagens. Maybe this is why, despite moving all the THX settings to the Expert Modes, we could never quite get the PQs to look the same - THX always looked better! I was told the Pros know about this, and don't use THX in association with the Lumagens. Us Amateur Calibrators - we don't know, so just spreading the word.

The Calman 5.1 Ver 1100 - Best Skin Tones Ever! That is until the next New Beta? My TV is getting so conceited as to how good it looks, it soon be impossible to live with!
