ADOBE PHOTOSHOP CS2 
User Guide 
The second and more flexible method is to use an adjustment layer. Adjustment layers let you experiment with color 
and tonal adjustments without permanently modifying the pixels in the image. The color and tonal changes reside 
within the adjustment layer, which acts as a veil through which the underlying image layers appear. You must use 
Photoshop to create and edit adjustment layers; however, you can view existing adjustment layers in ImageReady. 
To open a color adjustment dialog box 
If you want to make adjustments to just a portion of your image, select that portion. If you make no selection, the 
adjustment is applied to the entire image. 
Do one of the following: 
• 
Choose Image > Adjustments, and choose a command from the submenu.
• 
• 
(Photoshop) Double-click the thumbnail of an existing adjustment layer in the Layers palette.
To see your adjustments in the image before accepting them, select Preview in the color adjustment dialog box.
To cancel changes without closing a color adjustment dialog box, hold down Alt (Windows) or Option (Mac OS) to 
change the Cancel button to Reset; then click Reset. This resets the dialog box to the values it had prior to your 
changes. 
To save and reapply settings in a dialog box 
The Save and Load buttons in the Levels, Curves (Photoshop), Hue/Saturation, Match Color (Photoshop), Replace 
Color (Photoshop), Selective Color (Photoshop), Channel Mixer (Photoshop), Shadow/Highlight (Photoshop), and 
Variations dialog boxes let you save your settings and apply them to other images. The procedure for saving and 
loading a setting in the Match Color command is slightly different. For saving and loading settings in the Match 
Color command, see “To save and apply settings in the Match Color command” on page 304. 
• 
To save a setting, click Save in the adjustment dialog box you are using. Name and save the settings. 
• 
To apply a saved setting, in an adjustment dialog box, click Load. Locate and load the saved adjustment file. 
If you apply the same adjustment often, consider recording and running the adjustment as an action or creating a 
droplet. 
Correcting in CMYK and RGB 
Even though you can perform all color and tonal corrections in RGB mode and nearly all adjustments in CMYK, you 
should choose a mode carefully. Whenever possible, avoid multiple conversions between modes, because color 
values are rounded and lost with each conversion. If an RGB image is to be used on-screen, you don’t have to convert 
it to CMYK mode. Conversely, if a CMYK scan is to be separated and printed, you don’t have to perform corrections 
in RGB mode.
