Thanks, I'll take a look.  It is usually that it works fine, 
technically, it is just that it doesn't add that much realism.  It is 
usually more a matter of putting slighly darker color in the low areas 
that adds more significantly to the effect, irregardless of whether I 
vary the finish or not.  I is really a matter, I think, that I have not 
portrayed a subject (like Janet has) where the effect makes a noticeable 
difference in the overall look of the picture.
