After you've read through that, here's a hint: inside the
scattering-brackets (where you set the type and color of the scattering
media), use "extinction 0". That way, the media won't swallow any light, so
things might get very bright, but at least you see if everything is running
fine. Then slowly crank extinction back up to 1 to see if you like it. 1 is
realistic, but I personally often resort to using scattering and absorbing
media together to have full control of the scattering color, and the color
the media gets when the light is absorbed.
