The Art of Photographic Printing
Charles W. Hearn, Hearn's Studies in Artistic Printing: a Complete Manual of Photographic Printing. Philadelphia: Sherman & Co., 1877.
This complete manual of photographic printing is illustrated with six fine cabinet and promenade portrait studies from negatives made especially for the purpose by Messrs. Rocher, Bigelow, Kent, and Baker. The first four albumen prints depict charming little girls and the remaining two are of young women. Its author Charles Heard parlayed his years of experience as a “photo printer exclusively” into his role as the proprietor of “Hearn's Photographic Printing Institute.” An advertising section at the end of the volume includes pricing information for lessons, retouching, printing and other services.
