Now open Abode Gamma by going to the Windows “Start” button in the lower left of your screen and click on Control Panel.
Open your Adobe Gamma application (If you don’t see Adobe Gamma listed on the Control Panel window click on the “Switch to Classic View” on the left side of the window.)
If this is the first time you’ve used the Gamma Wizard you should choose sRGB IEC61966-2.1 in Description area. In future you’ll use the last profile you created. Click Next.
Now using your monitor controls and making sure you can still see the Gamma window adjust the contrast to 100%. Next adjust the brightness control so the the center box is as dark as possible without being black while keeping the frame bright white. You may need to adjust this setting further once you begin adjusting the color. The Brightness range can vary greatly from monitor to monitor depending on its age and quality. Click Next.
The wizard should automatically choose the correct Phosphors setting for your monitor. If you check the manual that came with your monitor and it says something different then change this setting. Click Next.
Set the Gamma line to "Macintosh Default 1.80". (If your PC video card doesn't support this setting then use the Windows Default 2.20). If you're using a PC your screen will become brighter and you'll need to click back 2 screens and readjust your monitor brightness. On this window you'll find one gray box and slider. clicking and moving the slider adjusts all 3 colors (RGB) balance and density evenly.
If you uncheck the "View Single Gamma Only" 3 color boxes appear with individual sliders. Clicking and dragging each of the sliders separately allows for fine tuning of each color channel.
Now while viewing the print under typical lighting attempt to adjust each color channel to match the print. when changing each color channel the density will also change so you may have to readjust monitor's brightness once again. Pay close attention to the skin and gray tones of the calibration print. It may take some time to get the images close. Remember it is impossible to match exactly the (transmitted light) of the monitor to the (reflected light) of the print. Our goal is to get you to the point of achieving consistent, predictable images. We recommend you leave your monitor during the adjusting for a few minutes, the human eye has a habit of accepting skewed colors after looking at them long enough. When you fill you've gotten as close as you can click Next.
On this window you want to select the "Monitor White Point" to match the 6500k setting you used when adjusting the monitor earlier. Click Next.
On this window you want to select "Same as Hardware". Click Next.
If you click on the "Before" and "After" you can see the difference from where you began to your new color settings. Click Finish.
After you click Finish a "Save As" window will open. As not to change any existing profiles you should create a unique "File name" each time you calibrate so you can keep track of your previous calibrations. We recommend typing Ramsey Resources and the date and the last ICC Profile you created will be the one you want to use in the "Description" window the next time you calibrate. Click Save and you have finished calibrating your monitor.
Depending on the age and use of your monitor the color will change with time. We recommend calibrating your monitor every 2 to 3 weeks to keep your images consistent. Using the ICC Profile you created during the previous calibration you shouldn't see a big difference in the Before and After from now on, only slight a variation.
You may now get one of the 2 above windows opening in Photoshop. In case of the "Missing Profile" select "Assign working RGB: sRGB IEC61966-2.1 and if it's "Embedded Profile Mismatch" choose "Convert document's color to working space".
Now that you've finished calibrating we suggest you send in a few images adjusted under the new settings. Once you've received the images you can fine tune the calibration to improve the accuracy of your color and density.
