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 travelers representing commercial firms now carry round a
stereoscope and set of photographs to illustrate their firm's
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. Many of the
earliest books, particularly those dating back to the 1900s and before,
are now extremely scarce and increasingly expensive. Pomona Press are
republishing these classic works in affordable, high quality, modern
editions, using the original text and artwork.
