“C'est un volume à lire, je dirai même à relire, car le Dr. P. H. Emerson émet des idées qui lui sont tellement personnelles, qui souvent contredisent si fort les idées généralement reçues, qu’il faut s’y reprendre à deux fois pour bien se rendre compte de sa manière toute nouvelle d’apprécier l’art photographique.... Il se compose d’une introduction, dans laquelle nous trouvons tout d’abord la preuve de l’originalité des idées de l’auteur, &c.... On le voit, le sujet est traité dans tous ses détails, et ajoutons qu’il est traité d’une façon très intéressante.... Il taut reconnaître que la lecture de ce volume s’impose non seulement à ceux qui s’occupent de photographie, mais à tous ceux qui s’occupent de l'étude des beaux-arts.”—Journal de l'Industrie Photographique.

“It is enough to say that we have read this beautifully got-up book with interest, and consider the opinions and many doctrines of the author very remarkable; and finally we can in good faith recommend the book.”—(Translation of part of review in the) Deutsche Photographen-Zeitung.

“A most enjoyable book to every true lover of nature.... Erudite, embracing a very large field ... this work must claim the careful attention of an earnest student ... the ordinary textbook of photography is superseded, and technique and practice is dealt with in a thorough and somewhat original manner ... the reader will find much which will be well worth careful study.”—Photographic Art Journal.

“‘Naturalistic Photography’ is a splendid contribution to photographic literature.”

Wilson’s Photographic Magazine.

“This book is highly to be recommended to those acquainted with the English language.”

(Translated from) Photographische Mittheilungen.

“Cet ouvrage si bien étudié sera lu avec grand fruit par les photographes amateurs, surtout auxquels il est destiné, car ils y trouveront les conseils pratiques dont ils tireront profit, soit dans 'atelier, soit dans les études en plein air.”—L'Amateur Photographe.

“The practical part of Dr. Emerson’s book is most admirable.... Dr. Emerson has produced some of the most superb work ever achieved by photography, and all who have admired his beautiful compositions are anxious to know his methods. He treats the subject in a clear and forcible way, and with much originality.... One reads and reads again with pleasure from page to page, and is often delighted with the novelty of presentation. The great virtue of Dr. Emerson’s book is its freshness. The reader is not wearied with reiteration of old hackneyed ideas and misapplication of stereotyped rules. It is a record of the author’s own opinions.”
