AUTHENTIC SCIENCE FICTION is it as easy to make a com- plete hash of things because of a misunderstanding or ignorance of these principles. Such ill-fortune is no longer excusable, for a cheap and efficient source of information is now available in PRACTICAL PHOTOGRAPHY by B. K. Johnson, published by Hutch- inson (Stratford Place, Lon- don, W.1.) at 8/6. This splen- did little book by the Reader in Technical Optics at the Imperial College of Science and Technology, very fully covers the entire theoretical ground of photography with a remarkably practical em- phasis. Theory is not put forward merely as theory— the fault with other books of this type—but is expounded with a firm view to applica- tion by ordinary people with ordinary photographic apparatus. The 144 pages of the book cover 14 sections (chapters), a bibliography and index. The index could, with advantage, be more detailed, and the text would be considerably enhanced by a few photo- graphs in addition to the plentiful line drawings. Most aspects of general photo- graphy are covered in the various sections. Special sec- tions deal with microfilm processes, photomicrography, stereo-photography, and colour photography. This is a book which, in addition to being easily readable, is marked with the further distinction of being useful. Zoo-going may not be as fashionable an occupation as theatre-going, but it has a very large number of ad- herents, and is becoming in- creasingly popular. The prac- tice is also becoming rather more intelligent in that it is ~ coming to be less and less a matter of merely staring at animals that one does not see in everyday life. People of perception are requiring to know more and more about the animals found in zoos— about their natural lives, the way they are captured and the ways in which they are reared in captivity. ANIMALS MY ADVENTURE iS just the book for such people. It is written by Lutz Heck, Director of the Berlin Zoo, translated from the German 133 comiclooks.cormn
