I have spent a long time making this image as smooooooth as possible.
THIS PICTURE IS HUGE!!!
It toke a dual core workstation 12 min to render.
Works very well as a background layer or mask.
I create these files from the background patterning of pictures I have taken. If I like the light and colours of the image copy it and render it into a wave-file. The files are originally rendered in the gia.
