Photomechanics: the road to photogravure
In the 1840s Talbot turned to the photomechanical reproduction of pictures; this work led to photoglyphic engraving, the precursor of photogravure. Rendering a photograph in printer’s ink made editions cheaper and avoided the fading of early silver prints.
February 1841
Patents the calotype
Talbot obtained an English patent for the calotype process and sold licences at £20 each, later lowering the fee for amateurs to £4 while professionals paid up to £300 a year; scientists saw it as a hindrance to scientific freedom. He justified his rigour by the roughly £5,000 he had spent on photography; for science the method was free, and Talbot himself published the first known photomicrograph of a mineral crystal.
August 1841
First licence goes to the miniaturist Henry Collen
Having announced the calotype, in August Talbot licensed the miniature painter Henry Collen, who became the first professional calotypist. The most celebrated practitioners of the process were Hill & Adamson.

Birth of his son Charles Henry
Charles Henry Talbot was born into the Talbot family; with his birth the nursemaid Eliza Frayland joined the household, later captured in the family calotype of 1844.
