A history and handbook of photography

"The wealth of illustrations makes this a very important book. Two photoglyphic engravings by Talbot which represent one of only about four publications with these prints; the Pumphrey plates with his detailed ad help pinpoint the prices charged for collotype printing at this time; the very unusual Amand-Durand relief heliographs of diatoms, a type of printing not usually associated with this firm; and the photogravure by Leitch, who used Garnier's method in England. These coupled with Talbot's and his son's texts regarding photography and photoglyphic engraving, make this a most important work."--Hanson Collection catalog, p. 59.
