The first step was adding the sky and raising the gamut of the image. Then I added a few layers of smoke (Fig.66).

I always try to search for different methods for post-production and compositing. So, for the creation of the DOF effect, I decided to use Photoshop and the Depth Of Field Generator PRO. This is an excellent plugin, which gives you the possibility of producing enough realistic chromatic aberrations. I also used Nik Color Efex Pro, which has excellent effects such as Glow, Vignetting, Film Effects, different effects of color correction and other great details. I did a few different variants of post-production, and then chose the best. Here is the result (Fig.67).

Conclusion
I live in the beautiful city of Odessa, which is located on the shore of Black Sea. So every summer I spend my weekends with my friends, resting on the beach. Once, on one of those hot weekend days, I was lying on the sand with my friends and we were talking about computer graphics. Of course, we don't always talk about graphic arts – we often talk about girls instead! – but that day we were talking about our hobby and work. While we were talking, I noticed two amazing girls had approached and were commenting on our conversation, which they seemed to think was really strange.
So I began to think about it and you know – it is so strange. Computer graphics is not a simple theme to talk about; it is not simply a hobby or a piece of work, it is something much greater – a separate organism. It is another world; a big world; a planet with its own inhabitants, with their own culture, history and language.
So have a nice day or night, have good ideas and great rendering and thanks for reading (Fig.68 – Fig.70)!
