Most of the people know this but some dont pay a lot of attention but it is a good effect...
These steps are going to demonstrate how to create a shadow
ish effect in photoshop
1. Create some text with a color
2. Create the same text with a color that you want as your shadow
Make sure that the layer of your shadow text is in the bottom of the text layer (step 1)
3. Move the new text (that you just created in step 2) under the text you created in step 1...
4. move this text a bit to the right, left, up or down according to your desired effect
you can do this with different colors to give different looks
P.S the colors used in this tut. might not be the best but.. they work
