This attractive book has nearly everything in a compact space that one could ask for: discussion of both water-soluble and dry pencils, paper types, tools, techniques and procedures, colour, and more. It also discusses using pencils with other media, which is helpful: pencils are particularly well suited to being used with other media, yet other pencil books I've found so far treat pencil work in isolation.
Included is a gallery of beautiful, striking examples of pencil art to inspire readers, and each of these works has a paragraph discussing their main features.
In addition, there is a gallery of subjects for the reader to use as photo references, a wide-ranging, nicely balanced group of still and action pictures.
I also like the fact that the same reference photos are drawn by two different artists (Jane Strother being one of them), so you can see different interpretations. An artist can be more or less abstract and free in using photos or painting scenes, and this book is helpful in pointing the way. It is not in the least anti-realist, but neither does it see blade-by-blade photorealism as the only valid artistic response to a scene; the fact that pencils can make fine marks should not put a brake on our imaginations.
I have a few coloured pencil books, and each has its merits. But if I could have only one, this would be it. In that way, this wonderful resource for artists deserves to call itself a 'bible'.
