I've been going through the book Digital Painting for the Complete Beginner by Carlyn Beccia, and playing along with the software (both Painter and Photoshop) as I read. Today I learned how to clean up an old scan and tint the pencil lines. I tinted the drawing in this post in Painter 12. I used Photoshop CS 5.5 to tint the blog banner. Simple, but different processes for each. (I won't go into them here. If you are using both of these kinds of software and are eager to learn lots of tips and tricks for illustration, I strongly suggest getting a copy of Beccia's book.)
Then I went a little crazy playing with the brushes and paper textures in Painter. Apparently it's possible to get just as messy in a virtual studio as a real one. Who knew?
I did not bother to save most of my sloppy efforts today, but here's one I don't mind sharing:
I colored this version with a diffuse grainy camelhair watercolor brush on handmade watercolor paper. The base drawing comes from an old sketchbook. A very old sketchbook. The model died about twenty years ago.
