How to Apply a Layer Effect in Photoshop CS6
In Adobe Photoshop Creative Suite 6, layer effects fall into a few different categories. You can add shadows, glow effects, beveled and embossed edges, and overlay colors and patterns, and you can, of course, tweak to add whatever special effects you want. Follow these steps to apply a layer effect:
Select your desired layer in the Layers panel.
Choose Layer→Layer Style and choose an effect from the submenu.
You can also click the Add a Layer Style icon in the Layers panel and select an effect from the drop-down menu.
An intimidating Layer Style dialog box with a ton of options rears its head.
Select the Preview check box in the top-right portion of the dialog box so you can see your effects while you apply them.
To accept the default settings, just click OK.
Or you can experiment with the settings.
You can use sliders or check boxes, enter values in the text boxes, and so on.
If you refine your effect settings, click OK when you finish.
Photoshop applies your effect to your layer, as indicated by the fx icon.
