View color values in an image
You can use the Info palette to see the color value of pixels as you make color corrections. When you work with a
color adjustment dialog box, the Info palette displays two sets of color values for the pixels under the pointer. The
value in the left column is the original color value. The value in the right column is the color value after the
adjustment is made.
Using Levels and Info palette to neutralize the tone of an image
You can view the color of a single location using the Eyedropper tool , or you can use up to four Color
Samplers to display color information for one or more locations in the image. These samplers are saved in the
image, so you can refer to them repeatedly as you work, even if you close and reopen the image.
Color samplers and Info palette
1 Choose Window > Info to open the Info palette.
2 Select the Eyedropper tool or Color Sampler tool , and if necessary, choose a sample size in the options
bar. Point Sample reads the value of a single pixel, other options read the average of a pixel area.
3 If you selected the Color Sampler tool , place up to four color samplers on the image. Click where you want to
place a sampler.
4 Open an adjustment dialog box (under Image > Adjustments).
5 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.
