You can’t use Tone Correction when the Pixel Depth is set to Black & White, Halftone is set to None, or Text Enhancement Technology is turned on (see Customizing Image Types for details).
Using the Color Buttons
You can use the Highlight and Shadow color buttons to select particular colors in the image for use as the highlight and shadow colors. Click a color button and move the mouse pointer over the preview image; the pointer changes to an eyedropper icon. Then click on a color that you want to use as the highlight or shadow color for the entire image. The color box beneath the setting turns to that color.
Using Tone Correction
You can use Tone Correction to change the pixel brightness in the midtones, highlights, and shadows of an image. This produces more detail in the image without dramatically changing it. Click the 
Tone Correction button in the Advanced window to display the Tone Correction dialog box.
