The book contains the essential basic concepts to understand the photographic process. The author is explaining all the concepts and rules photography is based on, giving a general theory.
Luigi's book talks about everything from f stops to file formats, the difference between JPG and TIF and how image scaling and DPI relate. His section on how camera, computer monitor and printer color calibration works is explained so well, you'll never forget it (just think toast). It even has in-depth explanations on photo composition, HDR (High Dynamic Range) photography, depth of field, printing your images, publishing, and more.
Luigi's English is pretty good yet his lovely Italian flavor and sense of humor still come through.
