Photoshop Tutorial on Color Policies
Use this tutorial to get a better grasp on what the three policies really do and how the warning check boxes affect the resulting behavior. Before you begin, be sure the Document Profile indicator is set by clicking the small black triangle seen at the bottom left of the document...
To start this tutorial, open the Color Settings in Photoshop by entering the Command/Control Shift K key command. Set your Color Settings to U.S. Prepress Defaults as seen in Fig. 9-5-2. Note that the RGB Working space is set to Adobe RGB (1998) and more specific to this tutorial, all the color policies are set to Preserve Embedded Profiles with all the warning check boxes on.
f you examine the document's profile indicator at the bottom of the document window, you will see it now says Untagged RGB . The preview of the image shouldn't look correct either! This is because Pho- toshop will use the currently selected working space, in this case Adobe RGB (1998), as a mechanism for previewing documents, which are untagged. The Dog_in_Bowl.tif document is in sRGB. However, since we discarded the color profile, it opens untagged. Photoshop therefore uses Adobe RGB (1998) (the color space set in the Color Settings) as the assumption for previewing this document.
