Hi gents,

Sorry to butt in here with something you've probably seen a million times, but we all have to start somewhere

Completely new to calibration, but I'm passionate about my movies and want the display to be as good as I can get it (within budgetary reason of course ). So I bought this today and am currently tossing up between Calman Basic and ChromaPure Standard. I'm leaning towards ChromaPure but I just want to make sure that it's going to be suitable, both for a total beginner (I hear good things, so I assume it's noob friendly, but just triple checking), for the meter above and for my TV (currently a Samsung F9000, with a projector to follow in the next year or so).

I should say right now that I'm colourblind (not severely, but enough to muddle things up). There's an argument that I may not need calibration at all in that case, but this being an enthusiast board I assume you get it (I know it's currently wrong, I want it to be right ). So that being said, and with this really being an objective tool that's going to tell me if a colour is correct or not without my eyes factoring into the equation, am I still going to be OK to use the software etc properly?

Thanks for your time, appreciate the help!

EDIT: I'm going to be needing a calibration disc as well... I see there's a specific Chromapure one, but being in Australia it'd cost a bit to get one shipped over (not to mention the time). On CurtPalme for example, the shipping actually costs more than the disc itself Any suggestions there?

Hi

After auto calibration for a perfect chromaticity CIE94 you need to adjust manually in radiance colors output CMS with the post calibration color gamut from chromapure ?

i think the auto calibration is good but for a perfect result, you need to adjust after? i'm right
my post CIE is not 100% inside "reference"

If YES, it's not a problem with 9x9x9 3dlut autocal?
let me know
thank you

We can provide the disc as a digital download on request so long as you have the ability to burn Blu-rays from an iso image. Yes, ChromaPure works well with this meter. I don't know how anyone other than you can answer a question about your ability to get a satisfactory calibration given your color-blindness. If you have a rudimentary understanding of the vocabulary and main concepts of display calibration, ChromaPure shuld be quite straightforward to use. The included Help file is quite good.

let me know.
To provide some perspective, the result of your 729-color calibration is an average dE of 0.6, with over 90% of the colors below a dE of 1.0. This is just about as good as it gets. You are focusing on the wrong thing, which is the result of a very few colors at the very edge of the gamut.

As we discussed, I don't know why these particular colors are problematic for your installation. I couldn't reproduce the problem, nor has anyone else reported this. Has anyone else had an otherwise excellent result with 729 auto-cal EXCEPT RGBCYM at the edge of the gamut at 100% stimulus having higher than expected luminance?

EDIT: If your display has an auto-iris, turn it off for calibration. A fixed iris is fine.

Thanks Tom.

EDIT: Sorted out via email
