Last year I started playing with Corel Painter 12. My painting skills in reality lean toward creating backgrounds for my journal pages and underpainting for my digital prints. All abstract, so I find this whole digital painting idea really challenging.
Jeremy Sutton has a wonderful website along with books and dvd's about the subject-Paint Box TV. He is truly amazing and while I am still fumbling along learning from him I am enjoying the process. Hopefully I will get comfortable with Painter and get enough time to master some of my own ideas.
