Digital BW, The Print

Hi,

I bought my Huey today. It is a cute, user friendly and affordable
little package. The set up was easy. The screen guides you through the
whole process. You need approx 5 minutes to calibrate your monitor.
Great - up to here! I do have some questions:

1/ I'm using Mac PowerBook G4 and and additional Lacie electron 19
blue IV monitor for editing my photographs. My small LCD computer
monitor is not important but how shall I calibrate my main (Lacie)
monitor? Is it an independent process? And if YES then how shall I
disable the LCD screen while calibrating?

2/ Ideally, I'd like them to match. But is it realistic? Can LCD and
CRT screens really match?

3/ Shall I leave Huey continuosly connected (to measure my room light
temperature)?

4/ Shall I calibrate in the morning or at night (I work under daylight
and tungsten just equally). And how often?

Thanks for your advice,

Vlad3

Pretty damn close, within their gamut limits. I managed to get my laptop to
look almost identical to my old CRT, much closer than my prints, but perhaps
the $1300 spectro had something to do with it.

How's the viewing angle on your LCD? Lesser colorimeters may have trouble
getting accurate readings if the LCD looks noticeably different, say, 30
degrees off axis. I don't know how good the Huey is in that regard, but I do
know that the Eye-One spectro is very forgiving in that regard.

Hi Paul,

Thanks for your speedy reply!  Could you please also answer my earlier
question: how to go through the process of calibrating an additional
monitor attached to computer LCD?

Regards,

I would have if I could have, but I don't use a Mac.

Yes, its fast because it skips measuring all the color channels, and makes 
estimations instead.

If your LCD is brighter than the CRT, you'll be in trouble, as it will steal 
your eye, and define white for you, making your CRT calibration ineffective...

Makes sense to me, if both can be run in the same brightness range 
effectively...

Not with sub-hundred dollar solutions, you really need more advanced software 
for   monitor matching and tuning.

Its like harnessing a donkey and a racehorse; as long as you don't mind 
donkey level results you might manage to make it work. In this case that means 
dimming your LCD down to the same luminance as your CRT, and working in very dim 
lighting conditions (as is always necessary with a CRT).

Even people that gave Huey a good review suggested turning this feature off. 
Do you want the shadow of your arm across the sensor to suddenly change the 
gamma of your screen? This is for gamers, for image editing, leave it off.

> If you are using a CRT with daylight in the room you are no under valid 
conditions for color management. Period. You need a controlled light situation, and 
a VERY dim one for a CRT to be effective. Even an LCD requires moderately dim 
light for good color matching. Hopping your monitor's gamma around is not 
going to magically make up for unreasonable ambient lighting conditions. Serious 
color matching requires serious ambient lighting control.

One more warning: its important to calibrate with the Huey in DARK 
conditions. Since the Huey does not mask a large circle around its measureing location, 
ambient light leaks into the measurements, effecting dark measurement results. 
So having it dark while calibrating is far more important with the Huey than 
with other monitor calibrators.
