STEREOSCOPIC PHOTOGRAPHY- ITS APPLICATION TO SCIENCE, INDUSTRY AND EDUCATION By ARTHUR W. JUDGE. Second edition published in 1935. PREFACE TO SECOND EDITION: SINCE the first edition of this book was written there has been a good deal of progress in stereoscopy, notably in its commercial and scientific applications there has also been a number of important developments in connection with the apparatus used for stereoscopic methods and photography. The present edition has been partly re-written and extended to bring it up to date in these respects no less than 94 pages have been added for this purpose. Whilst amateur stereoscopic photography has not made any noticeable progress in this country, there is still an appreciable number of keen workers enthusiastically pursuing this fascinating branch of photography. On the Continent, however, there is much more interest taken by the amateur in this work. The use of commercial stereoscopic photographs has extended considerably in recent years and many travellers representing commercial firms now carry round a stereoscope and set of photographs to illustrate their firms products instead of taking samples or flat photographs. One large electrical concern has found it profitable to have most of its spare parts photographed stereoscopically and the complete set of views sent to all its agencies in different parts of the world. There have been some important developments in the scientific side in connection with optical apparatus for examining the eye and the interior of the stomach, in microscopy, X-ray crystal analysis, X-ray examination of materials and persons, aerial survey work, etc. Most of these items are referred to in the present edition. A good deal of attention has been given to the subject of stereoscopic projection of cine pictures, in order to obtain natural relief effects upon the screen of the cinema. Although, from time to time, somewhat extravagant claims have been made for certain new systems, with the exception, perhaps, of Dr. Ives limited experimental solution of the problem, none of these appear to have been successful at the time of going to press. The section of the original edition on stereoscopic projection has been extended considerably and accounts are given of Dr. Ives new method and of Bairds television scheme for trans mitting stereoscopic pictures by wireless. In revising the earlier edition the opportunity has been taken to correct one or two errors that crept into it. In conclusion the author wishes to acknowledge the valuable assistance and useful suggestions of Messrs. W. E. Dowdy in connection with flower photography and microscopy and J. F. Stirling in regard to miscellaneous applications of stereoscopy and R. B. Willcock commercial photography. A. W. JUDGE. Farnham, 1935. CONTENTS: CHAPTER I INTRODUCTORY .
