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.

To English authors I am principally indebted for that portion of my
work relating to Photogenic drawing on paper.  To them we owe nearly
all the most important improvements in that branch of the art.
Besides, it has been but seldom attempted in the United States, and
then without any decided success.  Of these attempts I shall speak
further in the Historical portion of this volume.

Every thing essential, therefore, to a complete knowledge of the whole
art, comprising all the most recent discoveries and improvements down
to the day of publication will be found herein laid down.
