I have had many years of solid experience working with computer applications. I receive my master degree in Computer Science( in U.S.A.) and two more years in Ph.D (unfinished) of Computer Science(in Canada) too. Moreover, all of my jobs have been about IT; such jobs as NortelNetworks, government ,and University lecturer have granted me with the otherwise unattainable unique experience for writing this book perfectly designed for anyone who wishes to learn Photoshop CS5. I have been teaching at Colleges and Universities for 20 years, during which time I learned to pass on knowledge through the simplest and most direct manner. I am now a reputable author in Taiwan and I have published 7 books and 3 e-books (video tutorials from Learn Adobe Photoshop, Flash, and Dreamweaver in Chinese), and amongst them some often climb up to the top 30 best seller of Computer Textbooks in Taiwan.
