The book reasonably covers most of the ground relevant to landscape photography, is acceptably written and nicely illustrated. On the other hand, it can be tediously long and insubstantial before getting down to what you primarily came to it for, i.e. a thorough, clear, step-by-step discussion of the relevant techniques. Unlike this, their actual treatment is usually loose and shallow, often incomplete even for a basic-level text (e.g. fancy discussing exposure of high-contrast scenes on slide film based on midtone estimates without a single word about bracketing?), while the total absence of summaries, check-lists and other like tools greatly detracts from its possible pedagogic and future reference value. Plenty of nice pictures, yes, some great (that is, if you like Fuji Velvia's garish colours, which plague the book), and no doubt one can pick some ideas from them. But in a would-be photography manual what you expect from the pictures is, rather than beauty, an effective illustration of the approach and technique alternatives, which is limited in the book, and be provided with full details of at least the more significant shots, whereas here all you are given is lens and film, not even the exposure settings. Conclusion: more an inspiring picture book (three stars for this) than an effective learning tool.
All the same, useful if you do not know about basic exposure, what hyperfocal focusing is, what a polarizing filter does, when to use a tripod, the basic characteristics of various focal lengths, the basic effects of different lighting, basic ..., etc. But then what you actually need is a general photography handbook (see Michael Langford's, for instance), which will do better to one's vision and technique overall, including for landscape, through a more structured, systematic and complete coverage of these and other topics. If you are beyond that level, do save your money and look somewhere else.
