THE HISTORY AND PRACTICE OF THE ART OF PHOTOGRAPHY; OR THE PRODUCTION OF PICTURES THROUGH THE AGENCY OF LIGHT. CONTAINING ALL THE INSTRUCTIONS NECESSARY FOR THE COMPLETE PRACTICE OF THE DAGUERREAN AND PHOTOGENIC ART, BOTH ON METALLIC PLATES AND ON PAPER. By HENRY H. SNELLING. ILLUSTRATED WITH WOOD CUTS. New York: PUBLISHED BY G. P. PUTNAM, 155 Broadway, 1849. Entered according to act of Congress in the year 1849, by H. H. Snelling, in the Clerk's office, of the District Court of the Southern District of New York. New York: PRINTED BY BUSTEED & McCOY, 163 Fulton Street. TO EDWARD ANTHONY, ESQ., AN ESTEEMED FRIEND. Whose gentlemanly deportment, liberal feelings, and strict integrity have secured him a large circle of friends, this work is Respectfully Dedicated By the AUTHOR. PREFACE. The object of this little work is to fill a void much complained of by Daguerreotypists--particularly young beginners. The author has waited a long time in hopes that some more able pen would be devoted to the subject, but the wants of the numerous, and constantly increasing, class, just mentioned, induces him to wait no longer. All the English works on the subject--particularly on the practical application, of Photogenic drawing--are deficient in many minute details, which are essential to a complete understanding of the art. Many of their methods of operating are entirely different from, and much inferior to, those practised in the United States: their apparatus, also, cannot compare with ours for completeness, utility or simplicity. I shall, therefore, confine myself principally--so far as Photogenic drawing upon metalic plates is concerned--to the methods practised by the most celebrated and experienced operators, drawing upon French and English authority only in cases where I find it essential to the purpose for which I design my work, namely: furnishing a complete system of Photography; such an one as will enable any gentleman, or lady, who may wish to practise the art, for profit or amusement, to do so without the trouble and expense of seeking instruction from professors, which in many cases within my own knowledge has prevented persons from embracing the profession.
