WORLD HISTORY

Detailed explanation-1: -William Henry Fox Talbot was credited as the British inventor of photography. In 1834 he discovered how to make and fix images through the action of light and chemistry on paper. These ‘negatives’ could be used to make multiple prints and this process revolutionised image making.

Detailed explanation-2: -Photography was invented by Frenchman Nicéphore Niépce in 1822. Niépce developed a technique called heliography, which he used to create the world’s oldest surviving photograph, View from the Window at Le Gras (1827).

Detailed explanation-3: -The British inventor of photography, William Henry Fox Talbot (1800–1877), produced his first ‘photogenic drawings’ in 1834 and in the following year made his first camera negative.

Detailed explanation-4: -Louis-Jacques-Mandé Daguerre invented the daguerreotype process in France. The invention was announced to the public on August 19, 1839 at a meeting of the French Academy of Sciences in Paris.

Detailed explanation-5: -Talbot refined the chemicals used to sensitize the paper and created methods for fixing the image. Within 18 months of his initial experiments, he had grasped how to make these drawings permanent and, more importantly, developed the negative/positive process.
