Who discovered silver chloride in photography?
Nicéphore Niépce succeeded in photographing camera images on paper coated with silver chloride in 1816 but he, too, could not make his results light-fast. The first permanent camera photograph of this type was made in 1835 by Henry Fox Talbot.

How did William Henry Fox Talbot create his calotype photographs?
calotype, also called talbotype, early photographic technique invented by William Henry Fox Talbot of Great Britain in the 1830s. In this technique, a sheet of paper coated with silver chloride was exposed to light in a camera obscura; those areas hit by light became dark in tone, yielding a negative image.
What is Louis Daguerre famous for?

Henry Talbot devised the calotype in the autumn of 1840, perfected it by the time of its public introduction in mid-1841, and made it the subject of a patent (the patent did not extend to Scotland).
Who discovered latent image?
It appears that by 1835, three years after Niépce's death, Daguerre had discovered that a latent image forms on a plate of iodized silver and that it can be “developed” and made visible by exposure to mercury vapour, which settles on the exposed parts of the image.
Who invented stop action photography?
A major advancement for photography came in 1931 when Harold Edgerton (1903-1990) invented ultra-high-speed and stop-action photography. Edgerton used his invention to capture events too fast to see with the human eye, such as droplets of liquid splashing and bullets flying through mid-air.
When was the first camera invented?
Early fixed images
The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce, using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light.
Who experimented with paper treated with silver compounds in a camera obscura that led to the invention of the modern camera?
