Photoshop CS2's ImageOAdjustments menu includes a couple more, extremely powerful, ways to work with tonality in your images. You can use the Shadow/Highlight adjustment to isolate and change whatever range of dark and light pixels you want. By specifying what range of tonal values that you want to be considered dark or light, you control how broadly or narrowly your change is applied. The Exposure feature lets you change the overall tonality of the image, as if you'd taken the photo with a different camera setting. And don't forget about making spot corrections with the Dodge and Burn tools!

The Shadow/Highlight and Exposure adjustments are not the same as working with Raw images in the Camera Raw plug-in (see Chapter 7). Camera Raw works with unprocessed image data, the so-called digital negative. Using Photoshop's Adjustment commands, you're working with image data that has already been manipulated in the camera, by Photoshop, or both. When working with unprocessed data in Camera Raw, you truly have control over the exposure, the shadows, the highlights, and much more.

The Shadow/Highlight and Exposure adjustments are not available as adjustment layers. Changes that you make with these features are a permanent part of your image.
