You stated a multiplication of emission rgb by a "density". Hope you
aren't thinking this produces denser media. Looks like you may be
getting yourself on the right track though. Try raising the 'density'
rgb to compensate for lighter backgrounds while lowering the
scattering and emission (absorption also), you might even be able to
comment out 'scattering' completely, it's awfully slow anyway. The
variations of media environments is not easy to control from what I've
seen of it so far (nooooo :)  Good luck to you anyhow.
