This book summarizes all essential techniques for the intermediate to advanced amateur. If you own an SLR and at least a couple of lenses then this book will help you to learn or improve on your technique, and it will explain many technical issues in a clear style and with examples. There are chapters on working with light, on equipment and how to use it, on B&W and on colour techniques, on movement, on composition, on portraits, on studio techniques and on special effects. I like this book a lot and I quite often read in it or look things up to remind myself. If there is a caveat then it is that the first edition of this book was published in 1977, and this means that just a few of the more modern things are missing. (For example, I could not find anything on the difference between circular and linear polarizers. I had to look elsewhere to remind myself that both have the same effect optically, but modern AF SLRs use a polarizing beam splitter to split the light between AF sensor and meter, and you have to use a circular polarizer because otherwise you could cut off the light to either the meter of the AF.) The other slightly old-fashioned point is that about 20% of the book is dedicated to processing and darkroom techniques, which very few people still do themselves. Besides: having done B&W processing myself I doubt that anyone would really learn darkroom processing from this book alone. On the other hand, perhaps it is quite instructive for the uninitiated to learn how films works and how processing is done - even though their photo lab does it for them. On the whole: good read, good reference.
