How to Add a Shadow Layer Style in Photoshop
Layer Drop Shadows allow you to add a 3D look to a flat document. The effect is applied to all the elements on a layer.
Open a new document in Photoshop (File > New). Set the size to 500 pixels by 500 pixels at 72 ppi. Set Background Contents to White.
Select the Text tool, click the workspace and add your text. Set the Text Color to a non-white color.
Select the Text layer in the Layers menu and choose Layer > Layer Style > Drop Shadow.
Notice that the Drop Shadow heading is Bold and has a checkbox. Selecting any of the heading names will change the dialog box for adjusting the options.
The Structure section offers multiple Blending Mode, Opacity and Lighting settings. Make sure the Preview checkbox is checked to see your changes.
You can also control the Distance, Spread and, Size.
The Quality section offers Contour choices and Noise settings.
Copy/Paste Layer Styles
To duplicate a layer style, select the source style layer, choose Layer > Layer Style > Copy. Select the target layer and choose Layer > Layer Style > Paste.
Editing Shadow Settings
Double-click the word Drop Shadow below the layer name. This opens the Drop Shadow options box.
