The book really does start at the beginning, with a short history of the camera and photography, plus the basics of composition. But it progresses quickly into an overview of today's digital tools. Instead of bogging down the reader in myriad details about camera models, computer software and hardware, and other minutiae, the book gives an overview of the available technologies, describing which system or format is best for different kinds of tasks. This is a good thing--hardware and software evolve rapidly, and some of the details mentioned in the book as "up and coming" are now standard.
