A fractal is "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole" (Wikipedia).

If that definition doesn't make it clear for you, you can take a glimpse at this gallery, to see what a fractal is.

These fractals were done using Fractal Explorer y Apophysis, two freeware programs that run in windows.

These images are works done using photo retouching and editing or vectorial design, or a mixture of both of them.

I have used Photoshop for years, but since many years I use the Gimp, for the matters of Photo retouching. It's not as complete as Photoshop (or we could say that "is different"), but it fits my needs.

Talking about vectorial design, I have worked with Corel Draw, Freehand, but the software I use since many years is Inkscape, free as the Gimp,
a complete solution for vectorial design.

So here it is the gallery. There are different things, but it has a lot of logos.

Nearly all the images you can see in the Contests gallery were made using three programs: Povray, Moray and Hamapatch.
Some of these programs are now almost fossils (Moray and Hamapatch) for different reasons.

As I use Linux, the clever solution was to change and use Blender that is my main tool since 2006. Blender is a great piece of software.
It is free, under constant development and has a big (and great) community of users. Available for win, mac, linux...

I have worked with other programs aswell. The last qualification I got was related to 3DMax in 2009. Very good software, but out of my budget.

Well, these are the galleries.

Contests:

Old works submitted to contests, most of them to the Internet RayTracing Competition, a competition about 3D digital images running in the internet open to the whole world. Everybody can submit his images, professional or amateur and using any kind of 3D software (commercial, shareware or freeware). When I used to enter submissions to the Comp (1998-2003), there were a lot of entrants (usually 100 or more), but the contest disappeared.

Apart from that, there are some oddities, like the image I submitted to the Poster Contest for Bilbao's Fiestas in 2010. I link here the winner image so you can see how far I got form the target.

Others:

These are works of all my career, from 2018 to 1998. These were not submitted to any contest, were done for my own pleasure, or works for hire, most of them created with Blender. I hope you enjoy the selected ones.

Apart from that, most of the Wallpapers were made in 3D using Blender.
