Photogenic Drawing: William Henry Fox Talbot

Photo mapping is an invention of the initial camera program created by William Henry Fox Talbot. According to Malcolm Daniel, he invented a completely different photographic world during the industrial revolution (Malcolm Daniel, William Henry Fox Talbot (1800-1877) and photograph invention, Metmuseum.org). In addition, Talbot's innovation became the basis of the photograph from the 19th century to the 20th century. The concept of mirror painting has caused a lot of influence on the modern world.

A silver photograph invented by Louis - Jacques - Mande Daguerre in 1839 was officially announced in Paris, France. William Henry Fox Talbot announced a cameraless photography process called mirror picture.

At the same time as Daguerre's initial discovery, British scientist and mathematician Willim Henry Fox Talbot found a way to make a permanent image by exposing it to a thin paper that is alternately washed with sodium chloride and silver nitrate . In the first experiment of Talbot, the shape of the leaves was transferred to chemically sensitive paper. However, in 1835, Talbot produced a 1 in 2 negative papers photograph showing his ancestral home. Talbot stabilized the initial image with potassium iodide or salt, but according to the proposal by John Herschel like Daguer it was switched to sodium sulphate. Talbot called his image a top view, made a sandwich with silver-sensitive paper, and tried to create a positive image by exposing two sheets. The first image of Talbot was reversed (negative). In the process of remattering, he got a positive copy.

In the UK, noble and scholar William Henry Fox Talbot also tried photographing, and in the 1930's I made photographs of plant specimens from chemically treated paper. Talbot believes that photographs can provide valuable help for scientists and visually record the data for interpretation and experimentation. I heard that Daeger's process was announced in January 1839, and Talbot hastily announced details of his own way. The silver stereotype is quickly grasped by the clarity of the details (in fact it is clearer than the naked eye under the microscope) and this is for promoting the process of the French government, but this is the Talbot's negative positive papermaking process (standard This is the)) This forms the basis of all subsequent photography until the digital age. I will ask students, why do you think that negative processes and positive processes are very important?
