I wanted to simulate what http://www.berndnaut.nl/ and http://jamesturrell.com/ are doing in reality, but just by using the basics of 3ds Max and Corona Renderer. So I followed this tutorial https://www.youtube.com/watch?v=t6R3JwCy02M and I said to myself "Pretty easy! I can do this on a weekend". Well... I went through so many iterations of the cloud in order to make it look realistic that in the end, I spent over a month on this and that's why I named the image Taming A (Colourful) Cloud.
