Is there a good Photoshop tutorial on how to use layer styles when editing photographs?

[Bill Junk]

I'd like to find a really good tutorial, either in document form or as a video, that provides recommendations on creative ways to use layer styles when editing photographs.

@AaronNace has a great series on Phlearn:

Kevin,

Thanks for the suggestions.  I did find a couple very good tutorials on the PHLearn site but it looks like the one on layer styles is only available in the paid subscription option.  I was hoping to find something free.  Probably should have included that in my post.
