Software:
The Hand
While it technicly is hardware, my wacom tablet really lets me get physcal with my work.
Adobe Creative Cloud: Master Collection
All post editing and finish products that need that little bit of touch up is done in this.
As well as what I use for building sites, like this site, and my main choice for video editing and effects.
Lightwave 3D
LightWave 3D combines a state-of-the-art renderer with powerful, intuitive modeling, and animation tools.
This allows me to take my artwork into new media applications, such as film & animation.
e-on Software Vue 2015
An intense 3D application for creating digital environments with never ending forests, mountain ranges,
alien landscapes, oceans, vistas and even basic modeling. All of my newer artworks are created at least in
part by this software and because of that I have had my work mistaken for real photographs.
Terragen
A simple and cheap yet powerfull generator for creating photorealistic landscapes & scenery images.
Apophysis
Best way to create some mind blowing fractal flames and designs. Best of all its freeware.
