Limit the tonal range of brushed adjustments
You can limit the adjustment you’re about to brush on an image to a specific tonal range. For example, if you want to brush an adjustment on an image and have the adjustment affect only the shadows, you choose Shadows from the Brush Action pop-up menu and then brush the adjustment on the image. If the brush touches a midtone or highlight, that part of the image is not changed.
Tip: This feature is particularly useful when burning and dodging, because you can limit the exposure adjustment to the tonal range you want to modify without having to worry about adversely affecting details in the tonal ranges that are correctly exposed.
