We bought this book after getting an EOS 550D to bring on our travels. It’s a great way of exploring the features of the camera and learning something about photography at the same time. The first chapters covers the basics of both the camera and photography. As you read further you’ll learn more advanced features and techniques. The professional photographer would probably not get to much out of reading this book, but then again, they will probably not buy it. One aspect of the book that is especially good, is the assignments. After each chapter, the author gives us some assignments related to what we just learned. In stead of reading a booring instruction manual and a more general photographybook, you can save some time by reading this book.
