Using Layers to Create 3D Text
Here I've created the text I want to use. Go for a single, bold color rather than anything patterned or with a gradient to start off with, it makes it much easier until you get the hang of this process.
Now, duplicate your layer and change the color oh-so-slightly to a shade a bit darker than before.
Move your darker layer under your original text layer by clicking and dragging it downward.
Select your move tool, and click on your duplicated layer. Press the right arrow key on your keyboard once, and then press the down arrow key on your keyboard once.
Duplicate your duplicated layer, and once again press the right arrow key on your keyboard once, and then press the down arrow key on your keyboard once. Afterward, duplicate the layer you just worked with, and carefully nudge it over one pixel both right and down. Continue this process about ten times in total.
When completed, your text effect should look like this!
Look how easy that was! You created 3D text without any plug ins, artistic techniques, or expensive third party programs.
