   Sorry, I did a poor reading, and for the images I assumed too quickly your
problem was just the ultra-bright media... trying with your code on the last
message, I see that using extinction 0 gives the effect you are looking for.
But I still don't know very well why it doesn't works with the default,
teorically realistic, value of 1.

   I've a poor brain too, but I discovered it doesn't matters if you have the
power of unlimited "trial&error" at your disposal... ;)

P.S.: You still have the rgbf on the media, which doesn't works as you
think... and you even supplied some of the entries with 5 components colors!
(although it really doesn't matters for your problem).
