(File Size: 73.1 MB ) More on Adobe Gamma Calibration. QuickGamma 3.0.0.2. Data Added 1: May 19, 2012. QuickGamma is a small utility program to calibrate a monitor on the fly without having to buy expensive hardware tools. The relationship between the input signal and the luminance of a monitor is not linear but. Subscribe to signup for my newsletter and receive your FREE Quicktime Gamma Compensation LUT.

It looks perfect. Something undesirable is going on with your system or hardware. The gamma loader just resets this to the Adobe Gamma generated profile every time the system starts up, if it's in the startup folder. For this reason, there is absolutely no reason to use the method Tom suggests above. If you delete the Adobe Gamma from the startup folder, the same profile will still be used. Gamma is the relative bright and dark value of the image. Adjust the gamma setting by dragging the triangle icon on the Gamma color wheel in the Look panel. Drag clockwise to lower the gamma setting or counter-clockwise to increase it.
Follow these steps to use Adobe Gamma to calibrate your monitor:
1. First, turn your monitor on and let it warm up at least 60 minutes.
This action allows your monitor to stabilize before calibration.
2. Make certain that your monitor is displaying thousands of colors (16 bits) or more. If your monitor is set to 32 bits, don't change it.
3. Set your desktop display to a neutral gray using RGB values of 128.
If you're not sure how to do these two operations, check with your operating system documentation.
See 'Using a neutral background,' earlier in this chapter.
4. Set the lighting in the room the way you will have it when you are viewing images. Also try and reduce any glare or reflections on the screen.
5. Launch the Adobe Gamma utility.
This program ships with Album, but if you don't have this utility already installed, you can find it on your Photoshop Album installation CD. You can install it by opening the Adobe Gamma folder on the CD and following the simple install instructions in the ReadMe file. Adobe Gamma also ships with Adobe Photoshop, InDesign, and Acrobat, so if you have any of these applications, you may already have it installed.
You can find Adobe Gamma in the Control Panel (StartOSettingsO Control Panel). If it isn't there, check in your Program Files folder, in the Common Files folder, in the Adobe folder, in the Calibration folder.
6. You can select either the Step By Step (Wizard) option or the manual Control Panel option, both shown in Figure 10-2. I highly recommend using the Wizard. Then click Next.
The Wizard walks you through the calibration process via questions.
7. Adjust the monitor's contrast and brightness controls, which set the dark point of your monitor. Then click Next.
8. Enter the phosphors setting, for example, Trinitron. Then click Next.
If you don't know it, check your monitor's documentation.
9. Choose a gamma (gray or midtones) setting by adjusting a slider for red, green, and blue squares on-screen. Then click Next.
The default gamma for Windows is 2.2.
10. Set your white point. Then click Next.
The standard for Windows is 6500K (K stands for Kelvin, which measures color temperature).
Taking calibration to the next level
Each of us perceives color a little differently, so your visual perception could affect the way you profile your monitor. If you have a big budget and you really want to do a great calibration job, you might consider purchasing a self-calibrating monitor. These monitors constantly measure their own color and create a profile that is very precise. The technology comes with a price, however. These monitors are obviously more expensive than the average monitor.
If your budget isn't quite so hefty, consider a combination hardware/software calibration package that you can use with your existing monitor. You can get a pretty good package from several manufacturers, such as Pantone/Color Vision, which costs around $300. The package includes software that displays color swatches on your screen. Then you attach a photoelectric device, called a colorimeter, to your monitor with a suction cup. The sensors in the colorimeter measure the color, brightness, and other characteristics of the monitor. The software takes the data, adjusts your monitor to its optimum state, and then creates a profile from it. Very Invasion of the Body Snatchers. Very high tech.
You can start with the default settings, but they may need a little adjusting depending on what you see. When you're done, Adobe Gamma creates a profile of your monitor so your graphic programs know how your monitor is displaying color.
If you use the Wizard, Adobe Gamma allows you to see a before and after view of your screen. If Adobe Gamma has done its job properly, you won't see any funky color cast, and your monitor won't be too dark or overly bright. If everything looks good, you can click Finish. If not, you can go back and adjust.
