Wayne, Thank you for stopping by and your comments. Each presentation take hours, some time few days. Final rendering also not fast as I wish, even on GPU based rendering. Worst case scenario that final rendering does not match what was in mind...
Thanks to every one for your comments. Pierre, all this presentation done using fractal rendering applications. Software link: https://sites.google.com/site/mandelbulber/home
Pierre,
I should be clearer in what written before. I did write about classic car, that mostly have black color long time ago. Over time... well. it already written...
With all my best,
Grigoriy
