Adjusting color display for cross-platform variations

RGB color display on a computer monitor varies with the operating system used by the computer. For example, an image appears darker on a Windows system than on a Mac OS computer (because the standard RGB color space is darker in Windows than in Mac OS). The Preview commands in ImageReady enable you to compensate for cross-platform differences in RGB color display during image preview. In Photoshop, you can simulate cross-platform differences by using the Macintosh RGB, Windows RGB, and Monitor RGB commands in the View > Proof Setup menu. (See Soft-proofing colors.)

RGB color display can also vary between Photoshop and ImageReady. In Photoshop, you can select from several RGB color spaces when editing images. As a result, images created in Photoshop may use an RGB color space that differs from the monitor RGB color space used by ImageReady. You can adjust the RGB color display during image preview to compensate for differences between Photoshop and ImageReady.

To adjust RGB color display for cross-platform variations (ImageReady):

Choose View > Preview and choose an option for adjusting the color display:

• Uncompensated Color to view the image with the monitor gamma uncorrected
• Standard Macintosh Color to view the image with a gamma value of 1.8
• Standard Windows Color to view the image with a gamma value of 2.2
• Use Embedded Color Profile to view the image using the embedded profile

These options adjust color display only. No changes are made to pixels in the image.

You can edit your image in one window and view the same image with a different gamma value in a second window. Choose Window > Arrange > New Window for [file name]. With the new window active, choose View > Preview and then choose a different gamma than the one used in the first window.

To adjust RGB color display to match Photoshop color display (ImageReady):

Choose View > Preview > Use Embedded Color Profile.

Note: In order to use the Use Embedded Color Profile command in ImageReady, you must save the original image, with the color profile embedded, in Photoshop. Keep in mind that ImageReady does not use profiles in PNG or TIFF files.
