6 Color Matching in Adobe Photoshop (Version 7.0 or Later) Color Matching in Adobe Photoshop (Version 7.0 or Later) When an image saved in Nikon Capture 4 is opened in Adobe Photoshop, the profiles used in Adobe Photoshop should match those used in Nikon Capture 4. If the profiles do not match, the colors seen in Adobe Photoshop may not be the same as those in the original image. The profiles used with Nikon Capture 4 can be used with Adobe Photoshop version 7.0 or later. The first step is to match the Nikon Capture 4 monitor profile with that used in Adobe Photoshop (Windows only). The point to remember is that you should specify the monitor profile for Adobe Photoshop first and then select the same profile for Nikon Capture 4. For more in for ma tion, see Choos ing a Monitor Profile ( 267). Macintosh users will not need to perform this step. The next step is to save the image from Nikon Capture 4 using a format that supports inclu sion of color profile information. If you save the image in TIFF, JPEG (JFIF), or JPEG (Exif), in for ma tion about the color profile used in Nikon Capture 4 will be embedded in the file, and Adobe Photoshop will use this in for ma tion to process colors appropriately when the file is opened. For more information, see Ad just ing Set tings in Adobe Photoshop ( 270). Step 1 Choosing a Monitor Profile Choose a monitor profile as described below.
