Adding Fun and Useful Effects - Photoshop Elements 13: The Missing Manual - page 711

Here's a rundown of the choices available in each of the Effects panel's layer-style categor-
ies:
▪ Bevels give objects a 3-D look by making them appear raised from the page or embossed
into it. Figure 13-17 shows how just adding a drop shadow can add dimension to a
simple shape.
▪ Drop Shadows add shadow effects that make an object look like it's floating above the
page.
NOTE
To add a drop shadow to an entire photo, you have to also add canvas (see Adding
Canvas ) to give the shadow someplace to fall.
