The Tone Curve Controls
While the basic image-editing controls in Camera Raw are powerful, an additional adjustment is also provided, in the form of curves. If you’re accustomed to working with the Curves control in Photoshop, then Camera Raw’s curve edit will feel familiar. With it, you can perform additional tonal adjustments, to improve the contrast in your image.
Curves allow you to adjust the brightness of specific tonal areas in your image, making it yet another way to perform a type of selective editing.
To access the curve controls, click the Tone Curve tab in the Camera Raw window (Figure 5.14).
