Photography by Infrared: Its Principles and Applications

By Walter Clark | Go to book overview

Preface to the Second Edition

The printing plates for the first edition were destroyed in the air raids on London. It was not possible to remake the book during the war, and from some points of view this was an advantage for the new edition, because it gave time to acquire copies of the wartime literature published on the European continent.

Quite a lot of infrared photography has been done in recent years, and many new applications have resulted. Much more is now understood about its usefulness and limitations for the general photographer and the scientific and technical people. Great progress has been made with infrared films, which are now as fast and as stable as commonly used panchromatic films. The book has been thoroughly revised to inform the reader of these latest developments, and the extensive bibliographies have been brought up to date.

Among the changes made in the second edition are: a new chapter (XIII) on camouflage detection by infrared, and a new section on forest survey from the air; thorough revision of the sections on photography in the dark, measurement of temperature by infrared, the infrared focus of lenses, properties of paints and pigments with special reference to the examination of paintings, criminology, the properties of foliage in the infrared, medical photography and photomicrography, aerial photography, and modern sensitometry and systems of speed designation.
