I was talking about the “cast-shadows”,
and it was spelled out by Dwarg that in the age of global illumination it would be nice to be able to punch up the shadows on a per-object basis once in a while.
If we use many lights, the intensity of each light can not be too strong.
The cast shadow from one light is weak.
Some times we want a cast shadow which is not too weak.
It is nice to have, for instance , 300% shadow for the light source (Poser, and Vue can do it).

**As Miss Nancy pointed out, it does not obey the laws of optics.
Who cares ?
We are interested in art (just illusions), and not engineering.

I usually just reduce the ambient light to 0 and if using realistic sky, I cut down the global brightness.
 
The ambient light is important to have a nice skin of poser doll sometimes.**
