Penny Arcade examples of using computers for Art
Here are two great examples of using a computer to create digital art. The first is a slideshow on how an online comic illustrator uses Alias Sketchbook Pro to refine a sketch into a finished design. The link is here.
The second is a screencast of how to take a scanned sketch and turn it into an illustrated cartoon in Photoshop. There is no audio in this WMV movie, but it is very interesting to watch an artist at work! Here's the link.
The author of these tutorials is cartoonist Mike (Gabriel) Krahulik, the co-founder of the popular "Penny Arcade" comic strip and Web site.
