Modern photography began in the 1820s with the first permanent photographs.
Nicéphore Niépce's earliest surviving photograph, circa 1826.
The first permanent photograph was an image produced in 1826 by the French inventor Nicéphore Niépce.Produced with a camera,the image required an eight-hour exposure in bright sunshine.
In 1829 the daguerreotype was the first publicly announced photographic process.
It was developed by French artist Louis Daguerre together with Joseph Nicéphore Niépce. Niepce had produced the first photographic image in the camera obscura using asphaltum on a copper plate sensitised with lavender oil that required very long exposures.
After Niépce’s 1833 death, Daguerre continued to research the chemistry and mechanics of recording images by coating copper plates with iodized silver, in 1835 Daguerre discovered—after accidentally breaking a mercury thermometer—a method of developing images that had been exposed for 20–30 minutes. Further refinement of his process would allow him to fix the image—preventing further darkening of the silver—using a strong solution of common salts. The 1837 still life of plaster casts, a wicker-covered bottle, a framed drawing and a curtain—titled L’Atelier de l'artiste—was his first daguerreotype to successfully undergo the full process of exposure, development and fixation.
The image in a Daguerreotype is formed by the amalgam, or alloy, of mercury and silver. Mercury vapor from a pool of heated mercury is used to develop the plate that consists of a copper plate with a thin coating of silver rolled in contact that has previously been sensitised to light with iodine vapour so as to form silver iodide crystals on the silver surface of the plate.
Exposure times were later reduced by using bromine to form silver bromide crystals, and by replacing the Chevalier lenses with much larger, faster lenses designed by Joseph Petzval.
Photo Gallery contains nearly 500
photos of Derby and Derbyshire.
When viewing the daguerreotype, a dark surface is reflected into the mirrored silver surface, and the reproduction of detail in sharp photographs is very good, partly because of the perfectly flat surface.
"Boulevard du Temple",taken by Louis Daguerre in late 1838 or early 1839, was the first-ever photograph of a person. It is an image of a busy street,but because exposure time was over ten minutes, the city traffic was moving too much to appear. The exception is a man in the bottom left corner, who stood still getting his boots polished long enough to show up in the picture.
A modern day version of the daguerreotype photo.
Daguerreotype - Widely used from 1839 to 1855. The Daguerreotype was the first popular form of photography, images were captured directly on a thin piece of silver plated copper. Because no negatives were produced, copies could not be made so each image was unique.
1840 First American patent issued in photography to Alexander Wolcott for his camera.
1841 William Henry Talbot patents the Calotype process - the first negative positive process making possible the first multiple copies.
1843 First advertisement with a photograph made in Philadelphia.
1851 Frederick Scott Archer invented the Collodion process -images required only two or three seconds of light exposure.
