Add a Drop Shadow to a Layer?

Click on the Add a Layer Style icon (the fx icon) at the bottom of the Layers panel and, from the pop-up menu that appears, choose Drop Shadow. This brings up the Layer Style dialog and adds a drop shadow to everything on your current layer. To increase the blurriness of your shadow, increase its size by dragging the Size slider to the right. You could change the angle and location using the settings in this dialog, but honestly it’s easier to just move your cursor outside the dialog, right into the image itself, and click-and-drag the shadow right where you want it (this is pretty cool—give it a try). Once the shadow is applied, you’ll see the word “Effects” appear directly below your layer’s thumbnail in the Layers panel, and right below that you’ll see Drop Shadow. You’ll notice that both have an Eye icon to the left of them. If you click on the Eye icon to the left of Drop Shadow it hides the shadow from view. To make it visible again, click right where that Eye icon used to be. To delete the drop shadow altogether, click-and-drag it down onto the Trash icon at the bottom of the Layers panel. Okay, so what’s the “Effects” word mean? Well, a drop shadow is an effect (they’re called “layer effects”), but there are other effects you can apply to a layer, like a stroke effect, or a bevel and emboss effect, or an inner or outer glow effect, or a satin effect, and so on. You can apply multiple effects to a single layer (like a stroke and a drop shadow and a pattern). Clicking on the Eye icon to the left of Effects hides all the effects from view at once. Clicking on the Eye icon beside just one of the effects only hides that effect. Get it? (Got it!)
