The early history of photography

Have you ever wondered who was the genius that it all started? Have you thought would be, if we have the pictures?
Photography is meant by the word images, light, and monographs, the word that means creation. This word was used by Sir John Herschel in 1839. But the concept was created around 1000, when Alhazen invented the first pinhole camera, known locally as the Camera Obscura. It is the Latin translation of a darkroom. This is a black background, where a small hole or lens through which light rays from an object and a film or plate inside, where the image is produced. However, the invention has not been completed because the images were generated on the head.
Camera Obscura was mainly used for visualization and drawing. It was not until 1827, when the first photographic image was recorded with the use of Camera Obscura by Joseph Niepce. It was printed on the sun as a known photoetching. But the images were created by Niepce need eight hours of light exposure image and will disappear soon.
This was later improved by Loius Daguerre, whose goal was to reduce exposure and prevent the loss of pictures and names of the daguerreotype method.
Later, in 1841, Henry Talbot put the negative process and called calotype. The background is black, while the theme in shades of gray.
In 1851, Frederick Archer invented the wet-plate negative. Although this creates a more stable and more detailed is negative, its drawback is that you in a dark room with you wherever you bring the image must be integrated so that it dries before the emulsion was developed need.
She developed Tintypes by Hamilton Smith in 1856, giving a lighter shade than the calotype. Then in 1879, dry plates were invented which gave rise to the possibility of using a handheld camera.
In 1889, George Eastman created the roll of flexible film. Only in 1940, is the color films were introduced to the market.
These innovations have the future of photography, creating the printed image and the discovery of various photographic equipment we see today will be open.
