Making Larger Adjustments
The previous example required only minor changes to get the shadows where they
belonged. Some images require more extensive changes to adjust the shadow detail
properly. Because noise is more of a problem in the shadows, larger adjustments to

image in Figure 3.21 needs a large adjustment to the shadows.
By increasing the Shadows slider to 34, as shown in Figure 3.22, the bird and
fish both have better separation between shadows and midtones. They are also sepa-
rated from the blue sky a bit more.
