Problem with Eye-One 3.6

[Dinarius]

I have just upgraded the Eye-One software from 3.2 to 3.6.

I always use the Advanced calibration option.

My problem is that after adjusting Luminance and clicking the right arrow, instead of asking me to choose RGB Controls, it goes straight to the final Measuring stage.

This is very weird! Has anyone else had this problem?

Or has the RGB controls stage been eliminated in V3.6?

I am using Eye-One Display2/Eye-One Match 3.6 on a PC with XP Media Centre.

Many thanks.

Sorted.

I have just realized that if you choose Native White Point, then the Calibrate RGB option is removed from the menu on the left.

Silly of me, but they should point this out in the on-screen instructions nevertheless.

If you use an LCD then it may be a good idea to not use RGB buttons even if you have them and let the software do all adjustments via videocard LUTs. The reason is you don't want to combine the effects of two lossy remapping procedures. This does not apply to 10 or more bit LCD monitors.

And there's a very good reason to calibrate 8 bit LCDs to Native white point and gamma (at least the white point) - to eliminate  (or at least minimize) the use of lossy LUTs adjustments.

Serge,

Many thanks for the reply.

A few questions.........

If I am to follow your method (my monitor is 6 bit) which preferences do I choose?

1. In Eye-One Match, under Edit/General options, ICC profile version 2 is ticked. Should I choose version 4?

2. Small (Matrix) is ticked. Should I choose Large (LUT)?

3. Do I go the Easy or Advanced route? If the latter, what do I choose under White point and Luminance?

I am interested in creating a profile using your method and then comparing it to my existing one.

Many thanks.

ps........I also have a LaCie CRT monitor. Which perferences should I choose for that?

Yes!

[Dinarius]

Thanks.

But what about the other options/choices?

Oh... CRTs are different. You don't need to care about LUTs cause the signal is analog - you can adjust white point with buttons to your heart's content.

Don't know anything about ICC versions. Maybe "newer is better" but there may be some compatibility problems. Stick with default - it's a highly technical setting.

For white point   choose 6500K. (Or if you want to feel like an advanced calibration user a D65, it can be set using custom x and y coordinates to 0.313, 0.329 CIExy, which is very close to 6500K).

Gamma 2.2.

Luminance depends somewhat on your ambient light. 90-110 is the range often used for CRTs I believe. But mostly make sure to follow the brightness/contrast adjustments so you see all the steps on the greyscale ramp. At least measure what the luminance is right now without adjusting to get an idea.

Now, not sure if there are any theoretical disadvantages of adjusting gamma away from Native via LUTs on a VGA monitor - but this hardly a practical concern.

Serge,

Can I just summarise the Eye-One Match settings for LCD monitors too. Please correct if appropriate.

1. ICC Version 2.

2. Large LUT

3. Native White Point

4. Gamma 2.2

5. Luminance 120.

.......and then selecting No RGB Controls, thereby letting the video card do the work.

Correct?

Many thanks.

Serge,

Correct?

Sounds good. You can also futz with Native Gamma and ultimately the luminance once you start viewing prints beside the display.

digitaldog,

Brill!

Thanks.

Typically Native white point  is ideal for LCDs from image quality point of view and should be your first option. However if you percieve that your monitor has a color cast or you have to color match several monitors in non-colormanaged applications you can set a different target (6500K or 65K being a standard choice).
