I'm sure the density statement is completely logic,
I just dont quite understand it.
Sorry, if it is mentioned in the documentation.

In a density color_map "color rgb <0,0,0>"
is totally transperant, unlike in pigments.
Filter seems to have no funktion, neither do transmit.
So how can I make a partially black media?

Thanks,

The colors work differently with media.  Think of them as an amount.
Use an absorption media and <1, 1, 1> will be black.  I explain some of
this at:
