I have a friend who does a bit of illustration, but all by hand. He is not familiar with Photoshop or Illustrator. He would like learn a bit of Illustrator, just enough to get by and vectorize some of his designs.
I imagine he would need to understand the basic tools first(rectangle/ellipse,pen tool, etc.) then learn some techniques, based on the type of drawing he'll trace by hand.
Could you please recommend a clear/concise tutorial/series of tutorials focusing on vectorisation techniques ?
The can be online articles, chapters in books, video tutorials, etc.
