Great for bringing out shadow detail. You just have to play with the sliders to modify the default garish results!
Every now and then the fog settles below the level of our house, and this was the view this morning. I pretended we lived above a lake.
Frame made by adding a blank transparent layer and selecting all and putting a 15 pixel stroke around the edge, then going to Layer/Styles and choosing an inner shade; followed by another rectangular selection on another transparent layer, inside the previous selection, and stroking it with a lighter color (8 pixels for this stroke, then adding another inner shadow with layer/styles)
