By the way... I didn't mean to imply that your monitor was bad... It may
be fine- -I'm not familiar with that one and have no specific opinion. It
just sounded like it wasn't given much thought.

Welcome back, looking forward to see a few of those pix.

Sorry I can't help on the main question, the built-in monitor on my
iMac, with Spyder calibration, is right on, so I've never had those
problems.

Hi Roger,

The Samsung 204B is a gorgeous monitor, and after getting it set up, and
getting used to it a bit, I think you'll find it much more agreeable. You
may be reacting to the brightness of the display, rather than to the
contrast as such. Try toning down the brightness of the display, to 100
candela or so, and see if it's more like you were used to with the CRT.
Also make sure the color temp is set to 65K or less. If your video card
does not support digital output, you might consider getting one that does -
this is not a big investment as digital video cards start in the under 50
range.

Gamma affects overall brightness, and a higher gamma value trades away
contrast in the shadows for contrast in the highlights, but does not change
the overall contrast as such. Depending on your editing software, it may
make no difference at all in the appearance of the image. Programs like
Photoshop and Paint Shop Pro will compensate for your display, and give the
same image appearance for all gamma values.

Anyway, try cranking down the brightness.

Gee, Mark, I did say I was using a spyder 2. I also said I was planning
on getting a monitor more useful for photography. With the holidays
and planning for the Africa trip, I simply ran out of time upgrading
hardware so I would have the disk space and processing power for
the new images. I've returned with about 60 gbytes of images
from a stunning trip: >85 individual lions (I lost count), 13 cheetahs,
1 leopard, dozens of birds and other animals. Many mosaics to assemble,
even mosaics of cheetahs and other animals (3 to 4 frames to cover an animal).
Also, 3 frames to cover a bird with depth of field from tail to beak,
which will make for some interesting processing.
I'm still trying to choose the best of about 8,000 images.

I previously ran a spyder 2 calibrated sony CRT, but perhaps its the
10-hour jet lag (been home less than 24 hours) but I can't remember
my settings for the sony + spyder setup.

Following Mike Russel's advice, I reduced the brightness and the calibration
now looks better. In each case, I could see all steps in your brightness scale,
as I could my own scales, but images on my web site with any browser looked
way too contrasty. After reducing the brightness and recalibrating, things
look better (I may tweak some more). I used gamma 1.8 native in the spyder 2
setup. I tried a 6500 K color temperature but could not get a calibration
to reach that color temperature; but "native" worked ok (not stellar).
For example: this image:
http://www.clarkvision.com/galleries/gallery.large_format/web/c071099_...10_1e_t
still has blocked up reds on my LCD (see the enlarged flower below the main
image); reds that I could easily discern on my sony crt, and which print fine
on cibachrome and fuji crystal archive papers. This concerns me.
Maybe contrast is not the issue; perhaps its color gamut of the monitor?
Are LCDs that much different than CRTs in color gamut (lower)?

But it does make me wonder, with all the uncalibrated monitors out there,
how people perceive images on web sites. The factory settings for my
monitor were awful.

I've run a Philips Brilliance 202P4 CRT and an HP2335 LCD in spanned mode.
I calibrated them both with a Spyder2. I don't think I'd want to calibrate
only one. Because Windows XP doesn't support 2 different monitor profiles
directly, on boot-up I'd see the CRT without the calibration loaded into
the Video card's LUT for that monitor. I had to use the Spyder software to
load the profile into the LUT for the CRT. Once loaded, both displays
matched great but I'd hate to have to use them in the unmatched state. The
colour difference would be pretty disconcerting.
 >> Stay informed about: LCD monitor calibration 

Often, as posted above, the brightness of LCD panels compared to CRT and
reflective prints is the main problem calibrating for WYSIWYG printing.
Color matching per se is not as difficult. Also the ambient lighting in
which you view your monitor and your print can be significant factors
influencing your judgment.
The simplest solution is to calibrate your monitor in your preferred way and
print a test print (use your own suitable image or one of the many available
for download). Then turn down the contrast and brightness of your monitor
until there is reasonable match to the print. This may require a few trials.

Hi Roger...
My wife has a Samsung 204B and she no longer has any eye strain problems.
Whenever I use her PC to print to her dye-sub printer (an Olympus sRGB
printer), I always see more detain on her screen than the printer produces.
I think Mike is right in this... Take the time to get used to it.

My personal preference for a video card is the 2D Radeon work station card
hefty hit at $500+ but after paying out $5k for a camera, what's another few
hundred matter?

I myself use an old Viewsonic G90f+ (which is as old as the hills) for
working detailed images. I have a spare, new one in a box under my desk for
when it finally dies. I also have an Apple cinema which to be quite frank is
a little disappointing.

If I had to choose again, I would not have bought it. Instead, I'd have
opted for a screen with a very high (1000/1+ perhaps) contrast ratio,
regardless of who made it. I'd also take along a test image to see if it
really could display the detail I get from the CRT screens.

Now, all the cinema screen does is hold PS tools and menus so I have a clear
screen on the CRT. A waste I know. I would have liked it the other way
around but everything to do with image editing on a PC is a compromise of
some sort.

I use a 20 ince Samsung 204B, which replaced an Iiyama 20"
CRT that developed problems. The 204B is at least as good at
everything except color rendering.

Yes, and it worked fine. For photo editing, I think there's
a good case for running dual-monitor with a high-res LCD and
a color-calibrated CRT. (Though I have not yet set that up.)

I'm using a Lacie 321 (couldn't afford/justify the EIZO with Adobe RGB
gamut), and like it a lot. It covers almost the same gamut as my prior
Trinitron CRT did, and it is rather insensitive to viewing angle.
There is a slight non uniformity in the black levels but that's
probably inherent to the current technology.

Strictly gamma 2.2, and it calibrates to near perfection with the
EyeOne Pro.

> Any other advice/help is appreciated.

I suggest verifying the calibration result with a Gamma evaluation
test
target, like the 2.20 in the left frame from:
<http://www.aim-dtp.net/aim/evaluation/gamma_space/index.htm>
You can also compare with the 2.10 and the 2.30 to see which one is
closer, but the 2.20 should be the aim.

The Reds are very saturated on my Lacie 321 (similar sRGB gamut to my
prior Trinitron CRT), but not blocked up.

Might well be, since LCDs are quite different from CRTs. As you
presumably know LCDs selectively block light from a uniform backlight,
unlike CRTs which emit light from exited phosphors. That also means
that calibrating to native LCD backlight color temperature will give
the widest gamut, but for ICC conformity, 6500K should not be too much
of a sacrifice.

> Are LCDs that much different than CRTs in color gamut (lower)?

Some are, not necessarily your Samsung, but it might.
My Toshiba laptop has issues with Red reproduction, despite
calibration. It is also much more sensitive to viewing angle, so I'll
do my serious color work on the Lacie 321.

Most images will look nothing like they were intended to ...
It's not what I would call progress, but it is something to be aware
about.
It can be overcome with the more expensive offerings from NEC/Lacie
and Eizo (Graphic series).

Looking forward to your safari results,
Bart
