When the arthritis got so severe in my hands that I couldn’t hold a paintbrush any more I switched over to computer generated art. I can do everything I did with pen and ink and a paintbrush with an ergonomic mouse. I use Bryce 7 for the main work and DAZ 4.5 for most of the figures as well as Photoshop for touch-ups and other places like Turbosquid to get my models. DAZ is currently offering the composing software for free at http://www.daz3d.com/.
