I knew of M Kloskowski's work from seeing his video tutorials in the NAPP website so I knew what to expect.
As a relative newcomer to Photoshop, and keen to improve my skills, I found working with the book an absolute pleasure. There are downloadable files for the user to manipulate in the chapters, and each chapter delivers the subject matter in a simple and easy to follow manner, unlike many so-called self-help books I have used.
Within a few chapters I was designing my own fliers and brochures that I had previously employed a designer to do for me. That in itself repays the cost of the book. I would heartily recommend this to anyone wishing to get to grips with layers in Photoshop.
