Works for me . . .
A very nice place to start if you're trying to expand Photoshop skills into traditional art techniques.
Not for the serious artist
This book has mediocre instruction, and the example art is very very bad. I was very let down by the poor quality of both the instruction and sample art. I would say that both are not quite high school level, so I would not recommend this book to any even semi-serious artist over the age of 15 or so. The only difference between this book and a middle school level art textbook is that this book also covers very, VERY basic software information you can easily learn from many free sources or through a few hours of tinkering. It would probably be a good gift for a kid or perhaps someone who is undertaking digital art as a very casual hobby. If you are more serious than that about learning digital painting, I would recommend Don Seegmiller's book instead.
Photoshop and Painter Artist Tablet
The Photoshop and Painter Artist Tablet Book: Creative Techniques in Digital Painting
While I was not overly impressed with the art illustrations in this book I am very impressed with instruction. It explains the A-Z's of setting up your computer for Digital Artwork for both original art and photos. This includes setting up your pallates, naming/saving files, backup, etc.
Would recommend for newbies and experienced alike.
Painters Book
This book is a great guide to using the painters tablet with photoshop software. Very good reference.
A good book if you know Painter already
This is a small book that I bought in a bundle with my Wacom Tablet. The book is pretty good about showing you how to paint in Corel Painter and Adobe Photoshop, but you need to already know the software. There is no real "introduction" to the software. The book just assumes that you already know how to choose brushes and such, and takes you right into the painting methods. I like the book, but I don't recommend it to anyone who doesn't already know a bit about Corel Painter or Photoshop.
