Someone, someday, will write the definitive media tutorial, but I don't think
it's there yet.

Some general tips.

1. Test the 'shape' of your media-density using emitting media - much faster
than scattering
2. Unlike most aspects of POV, media is very sensitive to scale, but in general
the media colour/density will need to be a lot less than <1,1,1>. To get the
same thickness of media at different scales, divide the media colour by the new
scale.*
3. Use the defaults to start with.
4. Always try and use a container
5. Oh, and don't use rgbft 1 for your container's pigment - either rgbf 1 or
rgbt 1

* e.g.

sphere{
    0,1
    pigment{rgbf 1}
    hollow
    interior{
        media{
            method 3
            scattering{1, 0.001}
        }
    }
}

Scaled up by 10 would be:

sphere{
    0,1
    pigment{rgbf 1}
    hollow
    interior{
        media{
            method 3
            scattering{1, 0.001/10}
        }
    }
    scale 10
}
