CalMan 5 Release Notes and Discussion - Page 23

We don't have a PC calibration workflow for CalMAN 5 out yet, but you can add an ICC profile tool to any workflow if you have design mode.

Once you create the ICC profile, I believe MPC-HC can use it to do color correction.

I will try that out, thank you. You really are awesome for responding to posts related to your work outside of work hours and it's always so appreciated. Thank you!

Not to mention Joel is actually on vacation since Friday.

if i get the c3 with the tutorial software i can still use the 10 point IRE and color management options that my LG tv has in its expert picture settings or do i need to get basic. im a total noob but i learn quickly and dont really have the funds to get a pro calibration.

Feedback on 504:

> most of the select menus on the left hand side when setting up Color Cube WF are empty - they should contain all values and / or pre-select the meter / pattern / DDC setup the user has chosen before he opened the Color Cube WF template

> i1D3 was selected and used prior to loading of Color Cube WF - Color Cube WF gave me the option to INITIALIZE the meter - AFAIK not required for i1D3

> lots of times when I'm in either Quick Analysis or Color Cube WF using a Mini as pattern generator, when manually selecting "Gradient Greyscale" from the pattern menu, does NOT display the greyscale... also not on second attempt... I have to display a FULL WHITE pattern, and then selecting the greyscale pattern finally displays it

> in Color Cube WF - I created a few history snapshots (using the history tabs) of various pre-cal combinations - when moving on to the pre-cal evaulation (red / green flags) it used the first history tab as the data to display red / green lights... maybe use the currently active tab as that's the one user made a decision to move forward in the WF

> find below an Autocal greyscale attempt (using Mini) of a Sony RPTV, all settings at factory default - brightness, contrast, CCT, 30% / 100% white, dynamic range (clipping) set up correctly and all enhancements turned off before Autocal...




After careful consideration, I decided not to move on to do the 125-point CMS...

P.S.: After using a traditional greyscale & 6-point CMS calibration on the Sony as a base, CM Autocal was then able to improve things further utilizing the Mini...

questions regarding CM5:

What is the integration time (read interval) for the Klein K-10 A in CM 5 ?

Since the K-10 is not supported in CM Enthusiast, is it possible to add a meter license to enable support or must one upgrade to CM Studio ?

When calibrating a colorbox with CM5, how many points are read to create the 64^3 LUT ? Is the workflow for the colorbox the same as with the Mini ? Is it possible to manually tweak / edit the 21 point greyscale after Autocal ?


Thanks.

I received my CalMAN 5 Tutorial software along with my D3 colorimeter for my Panasonic 60GT30. Everything went pretty smooth, I performed gray scale calibration using custom mode on my display. I was going to use THX mode but I wasn't ready to enter SM yet, maybe later on. How should I store the D3 when I'm not using it? I placed it back in the original plastic packing.

For the Klein K-10(A) the integration time is set automatically by the meter and is usually 10ms to 500ms based on light level. We do also have meter exposure options within CalMAN 5 for sampling of 1 to 120 times for the K-10(A). By default for the K-10(A) our sampling is set to 5.

For the ColorBox you have options within CalMAN 5 to select how many luminance and saturations sub points you want to adjust. But in all cases the additional points are interpolated via 1 of 3 algorithms and the output Lut is always 64^3.

Yes you can always manually tweak the 1D ramps after a AutoCal. But once you have moved onto creating a 3D Lut in front of the 1D ramp you should not change the 1D ramp or the displays settings. We always work backwards from the display to the source. So in the case of the ColorBox it is Display->ColorBox(1D)->ColorBox(3D)->Source.

Does the same apply for the Mini LUT ?

Tweaking the greyscale right after it was Autocaled but before Color Cube would be okay ?

Thanks.

What should the low light handler be set to in CM be set to for the i1D3 for highest accuracy ?

Users have reported that some dark patches take almost 5 sec to read, so it appears it would be beneficial to set it to 5 sec...

What are Spectracal's recommendation ?

Thanks.

LLH values of 0.5 and 5 with a trigger of 1.

just to clarify:

standard exposure mode: 0.5 sec
low light mode: 5 sec
low light trigger: 1 cd / m^2

correct ?

maybe this should be set by default once an i1D3 is connected, I believe most of the Home Users out there have no clue which values to use...

Thanks !

Derek,

since the K-10 is not supported in CM Enthusiast, is it possible to add a meter license to enable support or must one upgrade to CM Studio ?

Thanks.

what's the size of the small and large patterns Calman uses when doing an Autocal with the Lumagen Mini ?

Thanks.

- M

I believe they are 2% and 11% by area.

For right now, it has to be an upgrade to studio.

We don't plan on creating add-ons for CalMAN 5.

2% of which area ? it can't be 2% of the active screen area...

Thanks.

Lumagen's Window Pattern Size:

Large Windows size: 11.11%

Small Windows size: 1.56%

% of the total screen pixels (1920x1080).

hmmm... I must be misinterpreting this data...

I'm trying to calculate the physical dimensions of the pattern window...

if the small pattern window is 1.56% of the active screen area then on my 65VT50 which has an active screen area of app. 56.41 x 31.69 (inches), a 1.56% window would mean a 0.88 inches (width) by 0.49 inches (height) pattern window...

that can't be right...

Large Windows size: 11,111111111111111111111111111111% = 640x360 pixels = 230.400 pixels
1920x1080 pixels = 2.073.600 total pixels

oh boy, got it...

if u can't get ur basic math straight, it's time to go to bed ... ;-)

Thanks !

This is a LUT cube 125/21 point GS calibration, I used the large window with my Mini, Profiled my C6 to itself, had the C6 about 7" away from screen for both profile and calibration.
Ues ISF mode in my VT50, set contrast 80, brightness 55, color 50, Screen brightness Normal, Color temp Warm 1, Gamma 2.2, all enchantments off.
I did not do my normal tweaking, if I did I could probably took care of the slight 20% and 90% rise/ drop.

Haven't you used both the small and the large window sizes in calibrating your 65VT50?

Given that you can make charts look essentially identical with fairly different settings and window sizes......which window size do you think gave you the most pop/contrast/best look?

Yes I can make all my calibrations look good and close to the same, and yes I have done both off and on screen profiling. But what I did here was to profile my C6 to my C6 off screen, using Calman 504 992 (beta), imo that's the interesting change in how I calibrate, Matter of fact the complete calibration was done with this beta..My norm is to profile my C6 off of my I1pro2.
Tonight I will use the C6 to C6 profile and run the same settings and same placement of the C6 I used for the above calibration, because I believe the Lum ramps have changed between 504 ver 992 and 993.
I am very happy with the results I got from the above calibration using ver 992 (beta), so if by using ver 993 (official) the calibration comes out the same I know its my profile and placement, if not then maybe its the difference in the lum ramp
btw, the blues are the best I have ever seen coming from my VT50. .

Why did you profiled the C6 against itself or are you talking about a 3D-calibration?

So you treat the C6 on screen as the reference meter?

- Rich

Well because I profiled it with the display I was going to calibrate, and it is my understanding that the C6 is profiled with a Konica Minolta CS-200 at SpectraCal. So what do I have to lose, nothing.
Before using Calman you could not do this, however the new CME5 you can profile the same meter using the display you are going to calibrate...


No but after I run the second calibration, I was planing on doing the profiling using the reference C6 with the glasses on and the target C6 with the glasses off. Just as I would if I was profiling my I1pro 2 and my C6 using the glasses.

If this type of profiling turns out to be the best way to go, then there will be no need to get a I1pro to profile a C6 with.

Anyway I don't want to get ahead of myself, I want to see the results of tonight's calibration and then a Glasses profile 3D and see how that calibration turns out. .

Also understand I am using a Radiance Mini 3D and a CME5 LUT cube (125 point cms/21 point GS).

Maybe you lose nothing, but imo it is very useless to profile the meter against itself in this way. You measured only the normal fluctuations of the probe and I think there is also a chance to get greater errors, using the profiled meter, because the fluctuations of the meters could be added in the wrong directions.

Profiling a meter against itself for a projector with the reference being off the screen, can give you better low light sensitivity since you will be measuring with the meter facing the projector.

This can be necessary if your meter struggles reading the lowest output for your projector off the screen. You are correct though, it does add more variables into the equation that you need to manage to get repeatable performance.
