The Bevel/Emboss effect is used to add rounded edges and shadows to give a 3D impression.
Depending on the type of bevel or emboss set, the rounded edge might be inside or outside layer content, convex or concave, and may include a shadow.

The following settings are shown when the effect is selected in the Layer FX Studio.
