William Henry Fox Talbot életében
A teljes életút1837 · Díj
Royal Society Bakerian Medal
1837. március 16.
Daughter born: Rosamond Constance Talbot
25 January 1839
First showing of photographs at the Royal Institution
Shortly after Louis Daguerre’s daguerreotype was announced in early January, Talbot asserted his priority and, at a Friday Evening Discourse at the Royal Institution, exhibited several paper photographs he had made in 1835. Within a fortnight he described the nature of his process to the Royal Society, while Daguerre revealed no useful details of his own until mid-August.
1840
Invents the calotype
Talbot found a way to print any number of positives on salted paper from a paper negative; new chemicals cut the exposure to a minute in bright sunlight. He called the method the “calotype” (from kalos, beautiful), informally the “talbotype”: unlike the daguerreotype with its single positive, it effectively created modern photography.
1840–1841
Post: High Sheriff of Wiltshire
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.
