This Photoshop tutorial goes over how to use displacement maps in quite a bit of depth.
Creating displacement maps is a fairly easy process, but the really fun part is really diving in and playing around with different blending modes, creating custom layer masks to refine the appearance of the displacement maps, and making sure that your work looks as good as it can on the surface in question.
This video covers a ton of Adobe Photoshop tips and tricks all in one, so hopefully it will be as useful to people who are new to Photoshop as it is to people who are veterans.
Fun fact: My cat attacked me several times during the recording of this video.
