Before my XP went walk-about (and the hard drive went with it) I was using a free editing program that allowed a "one-touch" (well, actually it was three clicks — but who's counting...) adjustment to the "relief" of a photo — which created a slightly more three dimensional look or depth-with-clarity — but I cannot recall the name of it. Anyone know?
What you refering as relief is as mattdm said a highlight shadow filter more like to give any object a stone-a-like surface look. What you are trying to ask is "Clarity" and/or "Structure". You can use snapseed which is free now after google bought it and there are many filters you can enjoy and very easy to use.
