Preface: "An abundance of excellent works on photography already exist, but, as far as the author is aware, there is no book in the English language which is adapted to the special use fo the Engineer, the Architect, and the Draughtsman, who may wish to employ heavenly light as a copying clerk....Parts of the following pages have been gathered from periodicals, portions are taken from standard works on photography, chemistry, and physics...[but] a great deal is original with the author. A large number of the formulas given have been practiced by him for many years." Includes very detailed information and formulas for a variety of processes (silver print, blue print, iron salt, chromium salt, etc).
