Adobe Photoshop CS3 How-Tos

I'm using Adobe Photoshop CS3 How-Tos, 100 Essential Techniques by Chris Orwig  for my HOW magazine project. This book is helping me a lot for this project, It tells you step by step what you need to do. This book is a key component of an overall design workflow that lets users work seamlessly among all of their graphics applications to create graphically rich content for print, web, motion graphics, and mobile devices.
