OF the two writers, both have zealously followed photography as something more 

 than a mere amusement, for a considerable number of years. One of the writers has 

 studied the science from a theoretical and experimental point, while the other writer's 

 attention has been almost entirely directed to the production of practical results by the 

 processes known, and by each process as it has been given to the world. As the joint 

 work of two acknowledged authorities in photography, and as every word in it refers to 

 subjects with which the authors are personally and intimately acquainted with not a 

 direction or a formula given on trust THE PROCESSES OF PURE PHOTOGRAPHY" possesses 

 a PRACTICAL VALUE that justly entitles it to become at once 



A STANDARD WORK. 



It not only contains the best of all the processes and methods which have been tried 

 by the experienced authors, but also includes MUCH THAT is NEW and has 



NEVER BEFORE BEEN PUBLISHED.
