Around the year 1800, Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance.

Thomas Wedgwood makes "sun pictures" by placing opaque objects on leather treated with silver nitrate; resulting images deteriorated rapidly, however, if displayed under light stronger than from candles.

Nicéphore Niépce combines the camera obscura with photosensitive paper
-
In 1816 Nicéphore Niépce, using paper coated with silver chloride, succeeded in photographing the images formed in a small camera, but the photographs were negatives, darkest where the camera image was lightest and vice versa, and they were not permanent in the sense of being reasonably light-fast; like earlier experimenters, Niépce could find no way to prevent the coating from darkening all over when it was exposed to light for viewing.
-
Called View from the Window at Le Gras, the oldest surviving permanent photograph of the image formed in a camera was created by Niépce in 1826 or 1827. It was made on a polished sheet of pewter and the light-sensitive substance was a thin coating of bitumen, a naturally occurring petroleum tar, which was dissolved in lavender oil.

The daguerreotype was the first publicly announced photographic process, and for nearly twenty years, it was the one most commonly used. It was invented by Louis-Jaques-Mandé Daguerre and introduced worldwide in 1839.
-
On 7 January 1839, this first complete practical photographic process was announced at a meeting of the French Academy of Sciences. Complete instructions were published on 19 August 1839.

In 1839, John Herschel made the first glass negative, but his process was difficult to reproduce.

James Clerk Maxwell presents a projected additive color image of a multicolored ribbon, the first demonstration of color photography by the three-color method he suggested in 1855

PhotographsEadweard Muybridge uses a row of cameras with trip-wires to make a high-speed photographic analysis of a galloping horse. Each picture is taken in less than the two-thousandth part of a second, and they are taken in sufficiently rapid sequence (about 25 per second)
