EMac Monitor Calibration Limits!

I have just invested in the ColorEyes Monitor Profiling system for this eMac and a G4 but find that the eMac's built in monitor has no independant control of anything other than contrast and brightness.
For serious calibration outside of using the Display Calibrator Assistant, there seems to be no way of altering the settings for maximum control via other profiling hardware and software.
Can anyone help...is there some alternative access to the monitors controls?

Go to /System Preferences, select Desplays, In the window that opens, at the top, should be three selections, "Desplay, Geometry, and Color". Select "Color" and then the tab on the left side that says "Calibrate" In the "introduction window threr is as "Expert Mode" selection.
Hope this is what you are looking for,
Gordon.

What exactly does monitor calibration do?

I have used a monitor calibration software (with a hardware colorimeter). I know it makes the display image "better". But I want to know more detail.
There seems to be two stages of improvement.
The first stage benefits everything that displays anything, including photos in browsers.
The second stage benefits only software with color management like photoshop.
What are the benefits for the for the first stage?
It changes the gamma or linearity of the display to 2.2 (for PC)
It removes color cast so that grey do not have a color tint.
Anything else?
I assume it is at the second stage (inside color managed software) that a photo would look the same across different computers and different monitors.
Why not turn on color management in windows so that all software are automatically color managed?
Does this also mean that inside a non color managed web browser (which is most of them), the same photo on a web page could look differently on different monitors, even if they are all calibrated by the same calibration software? But they still look more similar to each other than if they were displayed on un-calibrated monitors, right?

The correct terms for what you described as first and second are Monitor Calibration and Monitor Characterization or Profiling.
Calibration brings the monitor to a desired state by changing the behavior of the monitor or said in other words, alters how the monitor displays colors.
During the calibration process the monitor calibration software first changes directly or through the user all that is possible with the hardware controls of the monitor to bring its display to the desired state and then whatever was not possible with the hardware controls will be accomplished automatically also as much as possible by using the video card.
Profiling is first checking and then describing the display characteristics of the monitor in a monitor profile file. A monitor profile file, among other things, describes how the monitor displays color values like the RGB numbers. Profiling doesn't change the monitor behavior. The profile file is used by the color managed programs to change the color appearance of the images they use by sending the appropriate color values to the video card. These color values may be different from the actual color values of the image.
On theory, you don't need calibration in order to have properly characterized monitor. All the color managed programs need, is a monitor profile that describes how the monitor displays color values. However on practice if the monitor is calibrated as much as possible to a desired state, it can have much more and better display capabilities than a monitor without calibration. A desired state of a monitor is when its full capabilities can be used with certain display targets. These targets are specified by the user and are usually the white and black points, color temperature, and gamma.
To illustrate how a monitor without calibration can be a problem, I will give the following example. If you reduce only one of the RGB signals significantly, lets say the Blue, by using the hardware controls of the monitor then all neutral colors will become yellowish. With such monitor display, to get neutral colors, the color managed programs have to reduce also the other two signals Red and Green using the video card to the lowest denominator of the reduced Blue and this in general will limit the range of the entire color space available on your monitor. And since color management is about simulating on your monitor other color spaces (device and non-device specific) if you have limited display capabilities your monitor will not be able to adequately simulate other color spaces no matter how well the color managed programs try to achieve that. And also, as you already guessed that, in this example the non-color managed programs will display everything yellowish on such monitor because they don't have color management capabilities to correct it.

Help with monitor calibration - simulating NTSC on computer monitor

I know the proper way to monitor video is using an external NTSC production monitor. Since I don't have one I'm wondering how I can get the closest to simulating an NTSC monitor on my Apple Cinema Display. I have made a monitor calibration using gamma 1.4 that seems pretty good except the shadow areas are too dark. If I can resist the temptation to lighten the dark areas, based on what I see on my computer monitor, my results look pretty good on a TV played from a DVD. If there was some way I could set up my Cinema Display to be closer to an NTSC monitor it would help me a lot. Any ideas?
As a related question: If my video project is not destined for TV but played on a laptop and shown on a screen using a projector maybe I can use my computer monitor as more of a guide to what it will look like on screen.
Another related question: How do the modern flat screen TVs relate to the older CRT variety in terms of calibration. Do the new flat screens still use the same NTSC calibration? The flat screens seem more like computer monitors to me.

If the program won't be viewed on TV, using the computer monitor should be fine ... but keep in mind that Windows system's use a different gamma.
How do the modern flat screen TVs relate to the older CRT variety in terms of calibration. Do the new flat screens still use the same NTSC calibration? The flat screens seem more like computer monitors to me.
They aren't. They are designed to reproduce the NTSC/ATSC color space and gamma. However, like most later model consumer CRTs, flat panel TVs have built-in circuitry designed to artificially enhance/correct the image. That's the primary reason to use a professional monitor, be it a flat panel or an older CRT.

I have been having a issue with getting the colors on my monitor to match the colors fro my print lab. I now have the monitor calibrated to match the prints but when I open elements it doesn't use the same colors. If i have it use the calibrated profile by changing the color management settings, the color picker no longer shows true white or black. How do I get elements 12 to honor the new calibrated settings?

Ok so I've done what you said and this is what it's come back ....
I don't know that these are the errors , but they're the things which don't look right ...
Throughout the shut down there is a recurring line ;
It says ;
Com.apple.launchd 1 0x100600e70.anonymous.unmount 301 PID still valid
Then there are 2 more which I think are related ;
Com.apple.securityd 29 PID job has I overstayed its welcome , forcing removal.
Then the same with fseventd 48 and diskarbitrationd 13
Oh and on Launchd1 : System : stray anonymous job at shut down : PID 301 PPID13 PGID 13 unmount...
Then the last process says "about to call: reboot (RB_AUTOBOOT).
Continuing...
And stops ...
Hope this means something to you ... Thanks again for your help so far :-)

24" iMac - Dual monitor calibration

Just curious...
I have a 24" iMac Core 2 Duo 2.16Ghz, I am thinking of attaching an extrenal monitor to the system (non-Apple) and also borrowing a friends monitor calibration unit.
I've never had an external hooked up before and before I go buying one... my question is...
If I have a dual monitor setup (non-mirrored) can I assign each monitor its own monitor colour profile? or would I only be able to pick one and it applied it to both?
Thanks

Hi 75
Yes! Open the Display Preference and go to the NTSC/PAL panel for the attached display, then calibrate it just like you did the Internal.

Emac monitor goes black – slap brings it back to life

Last couple of days my emac monitor will just shut down and go black, just like an old TV tube packing up used to. It won't return on restart, but did return a couple of times after I took out mains lead from side of computer, let it rest, then tried again. However, today, this solution didn't work, but a tap to the side of the computer did get the screen going. I've read a number of different possible explanations for what might be the problem – everything from battery, to airport card to it's terminally ill, get a new computer, so don't really know what to do. Don't want to go and buy a new computer if all I really needed to do was change the battery. Any thoughts? Thanks in advance.

That's all good news. You have the later and better USB 2.0 eMac. However, the model is one containing groups of units affected by the logic board issues with bad capacitors. The logic board issues were most commonly associated with these serial number ranges:
G8412xxxxxx- G8520xxxxxx
YM412xxxxxx - YM520xxxxxx
VM440xxxxxx - VM516xxxxxx
[again, don't post your serial number here]
If yours is in the list, all you can do is keep an eye on it. Keeping it clean like you've done should help keep internal temps down and that may help longevity. The repair--if the shop can find an unaffected logic board---is nearly as much as a new Mac Mini.
If your board goes, and you are within driving distance of Salem OR USA, there is a shop that offers a low-cost repair of bad eMac logic boards rather than a replacement; it's much less expensive IF you don't have to ship a 50-pound computer round trip.
Your particular eMac can take advantage of newer, larger RAM modules that were not available when Apple engaved the specs in stone (Apple says 1GB max RAM). With the proper modules, you can increase RAM to a total of 2GB with two of these:
1GB PC2700 DDR 333MHz CAS 2.5 184 Pin DIMM
We have one of the above installed in my wife's USB 2.0 eMac alongside an original 256MB stick for a total of 1.25GB RAM and it's completely stable. However, you should get the RAM from the source I mentioned as they test in Macs. Similar RAM form a retail outlet may be PC-only.

LCD Monitor Calibration

There is an vast amount of information on this topic, that topic being LCD monitor calibration. Some LCD have presets, theatre, games, etc. I want to calibrate my LCD so that if someone else is viewing my work on their monitor and they complain it is too light or to dark, I can say it is your monitor. One of my LCD has two presets that are of interest 'standard' & 'sRGB' my other LCD doesn't have any presets. What is the best or near best calibration I can manually set both monitors too, if this is even possible on LCD, I hope it is, atleast I hope they have matured from the past.

I get into trouble with everyone when I suggest using a gamma calibration target and using on-monitor and video card controls to get the monitor calibration close to 2.2 gamma, so I probably shouldn't do it. But hey, it's not absolutely necessary to spend money to get closer to your goal. It really boils down to how good is good enough for you. Better color accuracy than what you have now could be a stepping stone.
One approach - and I'm not saying it's the best one, but it'll get you closer to your goal without spending money - is to set your monitor to the sRGB preset, set your monitor profile to sRGB IEC61966-2.1 in Windows, then adjust the video driver controls so that the gradients in this target, when displayed at 100% zoom, appear like neutral gray gradients.
This is what you want it to look like:
I wish I could say it's simple to get it to look like this, but unfortunately it's not. However, if you have the ability to set gamma, contrast, brightness for each of the three color channels in your video drivers (ATI Catalyst drivers offer this ability), then with a little elbow grease it is possible.

LCD Monitor Calibration Needed

I just purchased a 3rd party 19" LCD monitor, and noticed the the thing is freaking bright!
I need to calibrate this thing before it melts my eyes. I'm looking for either a tutorial on how to properly do this, or a program that will help me with this.
Any help is greatly appricated. Thanks!
--alan

if you've got the money for something worthwhile, the sypder2pro is an excellent monitor calibration tool. it calibrates crt's, lcd's and projectors. it actually allows me to use my 23" cinema display by removing most of the "pink" that the screen evolved to right after it went off of warranty, making it the most overpriced lemon i ever bought ($1799 before taxes).

Monitor calibration. Please help!!

Aloha,
I just downloaded the free trial of CS5. I am trying to use Adobe Gamma to calibrate my screen so that everything will print as I see it. I have already searched all about it. I CANNOT FIND IT TO USE IT. I cannot find where to download it.......I cannot find it already installed with the CS5. Instructions say that I have it when I download CS5 and for me to go under control panel and double click on the icon for it. I DONT HAVE IT. I only have the "Color management" icon which is already on my computer.
I am using Windows Vista 36bit.
A really appreciate your time with reading/responding to this tedious problem. Thanks!
-Brianna.

Not sure if you already found this answer somewhere else, but I found this article...the link for the entire article is...http://www.computer-darkroom.com/ps12_colour/ps12_1.htm I was also looking for the same thing, but I guess Adobe no longer provide Monitor Calibration...
Section 2 - Monitor Calibration and Characterisation
Monitor calibration and characterisation (profiling) is probably the most important aspect of a color managed workflow; yet many users seem oblivious to issues poor monitor calibration, etc can have on their documents. So, what is calibration, why is it so important, and why is it different from characterisation?
Calibration is a process whereby a device is brought to a standard state (e.g. a color temperature of 6500K and gamma of 2.2), whereas characterising the monitor is the process of determining how the monitor represents or reproduces color. We characterise the monitor by measuring how it displays known color values, then creating an ICC profile. The ICC profile is simply a data file that includes a description of the monitorsí color handling characteristics (i.e. its gamut). The calibration data will also be written into the ICC profile. As I've already mentioned, Photoshop then uses the monitor profile to automatically optimise the display of documents. It does so by carrying out an on-the-fly conversion between your document profile (e.g. ProPhoto RGB, Adobe RGB, sRGB, ColorMatch) and your monitor profile. This conversion does not alter the actual document in any way; just its appearance on the monitor.
Adobe stopped shipping Adobe Gamma with the Mac version of Photoshop a few versions back, but for a while kept it for Windows. This was because there was no software only alternative. Since Apple Display Calibrator Assistant was still installed within System Preferences Mac users never really found the absence of Adobe Gamma to be a problem. However, given that Windows Vista and Windows 7 don't play well with certain utilities, it was inevitable that Adobe Gamma would eventually be dropped from the Windows version of Photoshop. So, it came as no surprise that as of Photoshop CS3 Adobe stopped shipping Adobe Gamma, and it's still absent from CS5. For what it's worth, I think we can safely assume that Adobe will never again ship a monitor calibration utility with Photoshop.
Obviously, software only monitor calibration applications use the human eye to determine tone and color differences between a series of white/grey/black/color patches. However, it should go without saying that the eye isn't the most accurate method of measuring these differences. Therefore, my recommendation would be to use a hardware based system such as the DatacolorSpyderPro3, X-rite Photo ColorMunki or X-rite Photo i1 Display 2.
Tip for Mac OS X users: a tutorial describing the process of calibrating a display with the Apple Display Calibrator Assistant can be found here.
Useful Information on location of ICC/ColorSync Profiles
Photoshop CS5 is only compatible with Windows XP with Service Pack 3, Windows Vista or Windows 7 on the PC platform and OS X 10.5.7 or higher on the Mac platform. The upside of this is that the ICC and ColorSync profiles are more easily found.
Profile locations:-
Windows XP, Vista and Windows 7 - sub-folder named Windows\system32\spool\drivers\color
Mac OS X - ColorSync profiles are generally located in either the Library/ColorSync/Profiles or Users/~/Library/ColorSync/Profiles folder

Monitor Calibration & Lightroom 2

Hello, I have a problem. Normally I shot in RAW, edit the image, save a jpg (with sRGB Color space) resized for an on-line printing service and another jpg in full size and resolution.
Recently I bought a Spyder express monitor calibrator, so I have my calibrating profile called "spyder2express.icc" and I configured in windows xp my display to read this profile.
I edit a raw file with lightroom, but when I export to jpg and I look it with another viewer it doesn't look like the edited raw file, but it is mure saturated and different.
The same thing happened with Photoshop, looking the photo with the software is ok, but the jpg looked with xp viewer, ot faststone capture, or irfanview the jpg is different.
I'm sure that the profile is sRGB, so why this difference?
Is there anyone who can explain me what to do, and how to configure my computer?
Many thanks in advance

Just to clarify above the explanation by the others. Monitor calibration consists of two parts. One part is the calibration of the gamma curve. Gamma basically corresponds to contrast. This part is picked up by all applications and is handled by a correction table (called a LUT for LookUp Table) that is sent to your videocard. The second part is the correction for the gamut of your monitor. The gamut is basically the range of colors it can display. The gamut is determined by the actual wavelengths of red, green, and blue your monitor uses to mix the colors. This is different for every monitor out there and often quite different from sRGB. Some monitors have a much narrower gamut (most laptops) and some have a much wider gamut (the wide gamut displays that lots of people have now made by NEC, Samsung, Dell, etc.- my guess is that you have one of these). So even if you use sRGB, you still have to correct for this in order to display the right color on such displays. ONLY color managed apps do this. Lightroom is color managed as are many other apps such as Photoshop, Firefox 3.5, Safari, etc. However, many apps on windows are not, such as internet explorer, image viewer before vista, etc.

Pictures too dark - not a monitor calibration problem

I believe this is some kind of color space or EXIF data issue I'm having. The jist of it is this: if I view one of my pictures (they're in jpg format) in Windows Explorer, they look fine. But when Lightroom opens the picture or displays it in the library, it looks too dark. (Important note: this is not a monitor calibration issue. Searching on Google reveals tons of advice along these lines, but that's not what's happening here. Lightroom is simply displaying things differently than anything else.)
Photoshop had this problem also, but Adobe supplied a patch that made Photoshop ignore the color space EXIF data so my pictures would display "correctly". There does not seem to be any such equivalent fix for Lightroom. I'm using Windows XP - perhaps there's something I can do in the OS to fix this issue? I believe most of my pictures are sRGB.
How do I get Lightroom to display my pictures correctly? They are, of course, impossible to edit while they display like this. Thanks in advance for any help!

Thanks for the responses. I freely admit I don't understand color management. I also admit I have not calibrated my monitor. I know, therefore, that my colors are not perfectly synchronized across all my devices - and I'm fine with that for the moment, because they are close enough. What comes out of my camera, what is displayed on my monitor, and what comes out of my printer are all pretty close. I will calibrate soon and get even closer, but for now perfect color isn't my chief concern.
My problem is not that the colors don't match, it's that the pictures are too dark when displayed in Lightroom. By "too dark", I mean several stops of exposure too dark. A picture will display a certain way on my camera and in Windows, and the histogram reflects this. Then I load it into Lightroom, and while the histogram looks the same of course, the picture itself is being displayed like I took it at night. Hence, as far as I can tell, it's not a monitor calibration issue. If I were to calibrate the monitor to display the pictures in Lightroom correctly, everything else would look too bright, wouldn't it? Including Lightroom itself. Besides, it wouldn't be possible to brighten my monitor to the point that the pictures looked acceptable - that's how dark they are.
Here's another clue: if I'm at work, and I RDP to my PC at home, and open Lightroom in the RDP session, everything looks great. So, I'm thinking it's a Windows color space issue of some kind. The question is, since I admit I don't know much about color space, what might be the problem and how might I fix it?
So to summarize: incorrect color calibration isn't my problem (though I know it's something I have to do if I ever want to perfectly match output on my monitor and printer). The colors across all my devices are close enough for my purposes. Incorrect color isn't my problem at all. The problem is that Lightroom on my PC displays pictures as if most of the histogram was on the left, even when that's not the case. The pictures in Lightroom look nothing like they look on my camera, in Windows Explorer, or when printed on my printer. Why is that, and what can I do to fix it? Thanks.

Solution to clean the Emac monitor!

Does anyone know any solution to clean the emac monitor best beside the windex or iklear wiper?
thanks!

Vinh Pham,
Welcome to the Apple Discussions!
In general, don't use Windex; alchohol-based solvents can disolve the antiglare coating on CRT glass (whether an eMac or a flatscreen TV). Your profile shows 9.2.2 which says you have a first-generation nVidia graphics eMac; you can actually get away with using small (really small, as in barely moisten a cloth) amounts of Windex or the like, but it's not a good idea in general. You can actually get good rsults using nothing more than distilled water and a clean lint-free cloth. This was discussed recently in this forum; see JMVP, "CLEANING MY MONITOR" #1, 01:50pm Oct 22, 2005 CDT

Monitor Calibration question

Hi, I sarted a new job and they have an Apple 23" cinema HD monitor and a 12" Sony Triniton PVM-14N5U NTSC monitor. The computer screen looks fine but everything in the NTSC monitor looks aweful green.
Is there any kind of service for monitor calibration that you guys are aware of? like a company which will send professionals to our office to calibrate all the computer displays and all the NTSC monitors?
or should i buy one of those mousy calibrating thing. Is it possible to calibrate the sony NTSC monitors?
Please suggest me what should i do. Thank you people in advance.

Well... VERY early on in the fcp manual is a whole section on how to calibrate ntsc monitors.
No charge.

Choosing a monitor calibration tool

I realize this topic has been discussed before - but the products do get updated and change periodically, so I am asking for advice here on the current state of opinion - I am looking to calibrate dual Appple 23" monitors that work side by side.
They are pretty close right out of the box, but to improve things I have been considering the Monaco XR or XR Pro, ColorEyes & Eye One Display 2.
I imagine they all do a decent job of calibration, though I read somewhere that calibrating 2 monitors is not run of the mill for all calibrators.

I used the Monaco for several months before buying the Eye-One Photo. It worked well for the monitor calibration, although I didn't find that it was as especially good at matching my laptop screen to my Apple Cinema Display. The real problem for me was the method Monaco uses for calibrating the printer. I was not reliably able to print what I saw on my screen. Therefore, I bit the bullet and got the spectrophotometer (Eye-One Photo), which has done a very good job with both monitors and printer. While the Eye-One Photo measures the printer output (the print) directly, the Monaco relies on a scanner to tell it what the print looks like. This "indirect" measurement (necessary because it is not a spectrophotometer) led to inconsistent and inaccurate printer profiles.

I've heard good reports about Colorvision Spyder 3 Pro and I was impressed at a recent demonstration of the product. Also, it does not seem too expensive (about £100 here in the UK). There is also a higher spec version called Spyder 3 Elite.
I find it hard to answer your second point. Once you are happy that your monitor is giving you faithful colour representation, colour management is in the hands of the the processing lab that Apple has chosen to use, and this varies with region, of course. if it's any comfort, I have always been very happy with the results that I get back. However, the Photobooks that I have put together have all been for non-critical social and family purposes, rather than for any serious or professional use.
