It makes the light not illuminate media and not get attenuated by 
passing through media...media becomes shadowless to it. Scattering media 
is the only media that can reflect light, and both scattering and 
absorbing media can block light.

Your question isn't very clear. Are you having a specific problem?
Mainly it is just trial and error, experience, and progressive 
refinement. Start with something simple and build on it.
