Figure 5.18 The Shadow clipping warning turned on.

As you can see, this small loss of detail occurs in unimportant areas but does add the pure black necessary for a dynamic image. Local contrast is another consideration when processing your images. Setting a deep black and bright white with the Blacks and Whites sliders sets the overall contrast. Local contrast is controlled by the Contrast slider and the Clarity slider. The Contrast slider increases or decreases contrast in the midtones of the image. The Clarity slider increases or decreases contrast around tight edges. It is similar to sharpening but not as refined. I typically add from 5 to 20 points of clarity on most of my images. Too much, however, gives your images that crunchy look. Figure 5.19 shows the final image after adding +5 Contrast and +16 Clarity to increase the local contrast. I also used the Local Adjustment Brush tool to lower the contrast in the courtyard. Highlights in an image (especially those at a distance) should be lower in contrast and saturation than midtones and shadows. This helps keep the sense of reality.
