When you open the Curve tab in Camera Raw (see Figure 7-10), you can directly control the tonality of the image, just as you do in Photoshop's Curves dialog box. Keep in mind that this is in addition to changes that you make in the Adjust tab. The histogram you see ghosted behind the curve in Figure 7-10 represents the image's current settings in the Adjust tab.
Manipulate the curve by dragging the existing six anchor points, or click and drag to create custom anchor points. You can use the Curve tab to very gently adjust the tonality of your image or to radically alter the image, creating very interesting color effects.
