Sorry for the short delay of now some five years. I was occupied by some
RL issues a while and frustrated after loosing all codes by a headcrash
on a very new harddrive. Nearly, I had finished a very nice scene (The
Lonely Swan) and lost all the code. Later I experienced a very heavy
work load and at the beginning of this year a very severe disease of the
lung. Now I bought a new machine and thought that this open issue would
be a very nice test (core i7 vs. core i9). I rendered the image due to
Clipkas suggestions with diffuse albedo 0.5,0.4 on all balloons. It has
an little bit different mood since the colouring of the balloons is more
visible in the distance. The backside illumination has a severe
drewback: it doesn't work with the colour Blue.
