Adding drop shadows to text
You can apply a drop shadow to text. You can choose between two drop shadow styles: external, which places the shadow behind the text, or internal, which places the shadow inside the text.
You can also change the composite method for text or the drop shadow of text. For more information, see Blending layers by using composite methods.
