I have had good luck doing 2 things. 1 using a non linear color map, you dont
need to change your data, just the colormap to "do the same thing"  Second
changing the opacity on the colormap so that below a given level it is like 20%
so you only see ghosting, then above that level it ramps to 100% quite quickly.
 Then I combine that with slices that dont use the opacity input so you can get
detailed info on a slice.  

That is just what works for me.
