Thanks. I know what you refer to, it has to do with the media-
sampling parameters. The effect gets stronger in the distance
because the distance between entrypoint and exitpoint of the
media container gets longer and at the same time the density
changes more often.

Nope, the clouds are definitely lit from above, the arrow points
towards the position of the lightsource. I think you mean the clouds
middle-left in the image. These are so bright because they are near
the direction to the 'sun'. This effect is actually quite realistic,
i think.

Thanks very much,
i'll certainly use the clouds in future-scenes and publish the code
so that others can play with it, too.
