First I did not understand why you put your request at o-t. For sure, your image
is a photograph (cell-phone?), but you asked for ideas to model it. What is on
topic IMO. (If you would not need ideas you wouldn't it posted. I guess).
I have just finished an image with a screen wide "cloud" (see last tc-rtc round)
and run into several difficulties. Larger parts of the cloud are invisible using
df3-files derived from Gilles makecloud-macros.
In your photograph I see mainly two clouds: A cirrocumulus over the whole sky
and a cumulus with this red and blue lighting. I fear the red and blue lighting
you must achieve with lightgroups and spotlights to have the white as well. If
you will create such a cumulus you can use Gilles's macros but you will have to
use an other "ground" object as he calls it (a difference of scaled cylinders
should work in your case). Study his code as you have not always did. For the
cirrocumuli: I'm just working on a similiar setting (using Jaime's Lightsys of
course). It is a bit like the contrail I have in my last TC-RTC entry but I will
have more density at one end, which corresponds to your picture. It mainly
consists of a (turbulenced) crackle density.
Best regards,
Michael

I was being slightly ironic, I wasn't asking p.o-t for real suggestions
and the image appears here because (for once) I obeyed the rule that
images must _not_ be posted in p.o-t.
The real reason for posting the image was to show a few people, who
don't like London, how incredible it can look.

Personally, I prefer to use Jaime Piqueres approach with an occasional
look at people like Chris Horman etc. That said, your suggestions are
entirely welcome and interesting
