 Paul, that is called 'bumping'. Very useful when trying to open shadow/deep areas on 
transparency. You could 'color' the bump with filtration to somewhat change the deeper hues.

Have you ever tried 'laintensification'? It has been many years but I do remember that 
working very well with good linear results. It was a post capture pre-process intensifier.
