19400 Photographic Researches and Manipulations,
Including the Author's Former Treatise on Daguerreotype

HILL, L.L.
A second edition, revised and enlarged,issued in 1854 by
Myron Shew in Philadelphia. An extremely scarce book.
Rebound Hardcover. 4 ¾” X 7 ¾” black calf with gilt
lettering and marbled paper over boards.  198pp. Very good.
Tight-hinged and fully handleable, dampstained on the title
page and some early pages; text block lightly age toned and
occasionally foxed.

First of this edition, tight and fairly nice, being a revised
edition of his 1850 "Treatise on Daguerreotype." In 1851,
upstate New York minister Levi L. Hill (1816-65) caused
controversy when he claimed to have developed a process to
create color photographs, which he called "heliochromes"
(and which soon became personalized to "Hillotypes"). It
wasn't until 1856 that Hill published his "Treatise on
Heliochromy" to explain the process, but a daguerreotypist
got the book banned on grounds of libel and all but a few
were pulped. Hill's process was long discredited, then
forgotten, although recent scientific tests show that his
convoluted process works somewhat.
The entire proceeds from this sale will go to the Daguerreian
Society though a generous donation by a Society member.
You will not find a lower cost volume of this scarce book.
