Prefrace

In the following pages the author has aimed to collect in
easily accessible form, information and formulas connected
with the production of photographic prints. His purpose has
been to impart the information in the simplest and most prac-
tical way possible, and to avoid errors in the numerous form-
ulas given, all of which he believes will stand the test of ac-
tual use. Sufficient material was collected to have filled double
the number of pages of this little volume, but since to have
done so would have been unduly to have increased the cost of
the book without enhancing its usefulness, the writer has ex-
ercised his best judgment in the selection of the material at
his command, giving only those methods which his own prac-
tice or that of others commended as useful and practical.

The work is rather one of compilation than of original re-
search, and the author has not scrupled to make use of the
work of others, giving due credit wherever the sources of in-
formation were known to him.

The opening chapters on the ” Theory of Light” and its
“Action on Sensitive Compounds” are merely condensed from
“Abney’s Handbook of Photography,” and are given for the
information of those who may care to know something of the
chemical changes produced by the action of light upon the
compounds most commonly used in photographic printing.

The author’s best thanks are due to Mr. W. I. Lincoln
Adams and Dr. Charles Ehrmann, of the Photographic
Times, for the very valuable advice and assistance which
they have freely given him, and for their careful reading of
the proof ; also to Mr. C. W. Canfield, for books furnished by
him which were of great assistance in writing the chapters on
” Carbon Prints” and ” Photo-ceramics.”

In conclusion, the author ventures to express the hope that
the following pages may prove useful to his brother amateurs
to whom the book is respectfully dedicated.
