Hi to the crowd again,

since I lost all the code of the original approach of this image due to 
a headcrash, I had to restart this scene from scratch. Only the 
erroneous density I posted here was left and the corrections Thomas and 
Alain proposed of course. Here is the actual WIP. I wondered how a white 
sun can cast yellow beams, but I took this RL image

https://de.wikipedia.org/wiki/Sonnenaufgang#/media/Datei:Sonnenaufgang_penon_de_ifach.jpg

as a basis for the sky_sphere, the sun, and its reflections. I failed to 
model this thin slice of white in the reflections in the original 
photography so far. But I think to "forget" it, is a venial sin.

I plan to add some pines, cattails, gras, broom, and the swan of course, 
but nothing more. The steam fog over land will be invisible after the 
addition of the plants (hope so). Additional suggestions are welcome as 
ever.

At the moment the rendering time is manageable: some hour with 16 
threads at 3.6 GHz (intel core i9).

Best regards
Michael
