This is a vintage 1989 book by Paul Cox titled Beautiful Ambrotypes.

Published by Travelling Light, UK. Hardcover. First edition. 40 duotones.

The duotone photographs in this book were drawn from private and public collections in Britain and the USA.

In 1834, Henry Fox Talbot created permanent negative images using paper soaked in silver chloride and fixed with a salt solution. He created positive images by contact printing onto another sheet of paper. In 1841, he patented his process under the name 'calotype'. In 1851, Frederick Scott Archer, a London sculptor, improved photographic resolution by spreading a mixture of collodion (nitrated cotton dissolved in ether and alcohol) and nitrate chemicals on sheets of glass.

In the United States, ambrotypes first came into use in the early 1850s. Building upon the wet plate collodion process by Talbot and Archer, ambrotypes used the plate image as a positive, instead of a negative. In 1854, James Ambrose Cutting of Boston took out several patents relating to the process. He may be responsible for coining the term 'ambrotype'. The ambrotype process was to remain the principal method of photography for the next 1/4 of a century, superseding both the daguerreotype and calotype within a few years.
