This technique seems to combine several renderings to a final picture.  The
Povray equivalent would be using the post_process function.  

For example: seperate rendering of clouds, sky gradient, sun glow (media), lens
flare and combining them with post_process.  

It's definitely worth trying, but on the other hand, the light does not
influence the clouds directly in this technique, so it can't simulate the
"glowing" of clouds on the side directed towards the sun.  

The nice thing would be, that you don't have to rerender the time intensive
parts (media clouds) when you want to change for example the lens flare/sun
glow.
