Adding Layer Styles
Like filters and effects, Layer styles let you transform objects by giving them new characteristics such as drop shadows. Layer styles are especially useful for modifying individual objects like text and buttons, because you can edit the text and change the button's shape even after you've applied the Layer style.

Figure 13-14 shows what you can do with Layer styles.
You apply Layer styles from the Effects panel (Window → Effects). Click the Layer Styles button (which has two overlapping squares on it) and then—from the drop-down menu—choose a category or Show All. Finally, select the layer you want to modify (by highlighting it in the Layers panel), and then double-click the thumbnail for the Layer style you want to use, or click it once and then click Apply.
