Open an adjustment dialog box (under Image > Adjustments). 
Make your adjustments in the dialog box and, before applying them, view the before and after color values in the 
Info palette: 
To view color values using the Eyedropper tool 
, move the pointer over the area of the image you want to 
examine. Opening an adjustment dialog box activates the Eyedropper tool outside the dialog box. You still have 
access to the scroll controls and to the Hand and Zoom
 tools using keyboard shortcuts. 
To view the color values under the color samplers, look at the lower half of the Info palette. To place additional 
color samplers in the image while the adjustment dialog box is open, Shift-click in the image. 
The Color palette also shows the color value of pixels under the eyedropper. 
To move or delete a color sampler 
Select the Color Sampler tool 
Do one of the following: 
To move a color sampler, drag the sampler to the new location. 
To delete a color sampler, drag the sampler out of the document window. Alternatively, hold down Alt (Windows) 
or Option (Mac OS) until the pointer becomes a scissors and click the sampler. 
To delete all color samplers, click Clear in the options bar. 
To delete a color sampler while an adjustment dialog box is open, hold down Alt+Shift (Windows) or 
Option+Shift (Mac OS), and click the sampler. 
To hide or show color samplers in an image

Understanding color adjustments 
Making color adjustments 
All Photoshop and ImageReady color adjustment tools work essentially the same way: They map an existing range 
of pixel values to a new range of values. The difference between the tools is the amount of control they provide. For 
an overview of the color adjustment tools, see “Tonal adjustment methods” on page 275. 
There are two ways to adjust the colors in an image. The first is to choose a command from the Image > Adjustments 
submenu. This method permanently alters the pixels in the active layer.
