IMAGE DESCRIPTION: 


This is the first real still image that I've created since I downloaded pov-ray

and moray for windows three weeks ago.  I have essentially used this competition

as a basis for a project in which I could learn what the tools at my disposal
are 
capable of and getting to grips them.  There is clearly substantial room for 
improvement of my image and many things that I wish I had included or tweaked a

little but which have not.  The reasons for this are manifold: time-constraints,

lack of experience with the program etc..  Altogether I am reasonable pleased
with 
the image as a first attempt.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


The image is largely a collection of bezier patches, with the occasional cameo 
appearance of a Sphere, Disc or Rotat.  The Tornado section itself is made from

3 main bezier cylinders, moulded into an appropriate shape and position and then

given a sky-type of texture.  

You'll notice that the vast proportion of the image has a certain misty quality

to it - which was provided through the use of a Rotat.  I was in two minds about

adding this because all other rendered images that I have seen have this certain

crisp, almost perfect characteristic.  But then again a 'Tornado scene' is by 
definition unsettled and chaotic, and if I had entered a nicely 'polished image'

I feel that it would have taken away a sense of dynamism that the scene needs to

make it look realistic.

The brightness and gamma correction of the image was tweaked using Corel's 
Photo-Paint 5 in accordance with rules 5g (ii) and (iii).
