Photography is the art, science and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor or chemically by means of a light-sensitive material such as strong photographic film. As far as can be ascertained, it was Sir John Herschel in a lecture before the Royal Society of London, on March 14, 1839 who made the word “photography” known to the world. But in an article published on February 25 of the same year in a German newspaper called the Vossische Zeitung.

History of photography
The first permanent photograph was made in 1822[2] by a French inventor, Joseph Nicéphore Niépce, building on a discovery by Johann Heinrich Schultz (1724)  Long before the second photographs were made, Chinese philosopher Mo Di and Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries. In the 6th century AD, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments. Invented in the first decades of the 19th century, photography (by way of the camera) seemed able to capture more detail and information than traditional mediums, such as painting and sculpting.[15] Photography as a usable process goes back to the 1820s with the development of chemical photography.

Color photography is almost as old as black-and-white, with early experiments dating to John Herschel’s experiments with Anthotype from 1842, and Lippmann plate from 1891. The final revolution of the 1800′s took place when a man named George Eastman developed the idea of converting the preprocessed plate into rolls of sheets that were mounted on a roll holder inside of the camera. He innovations which have evolved from this point on have made picture taking easier, improved the ability of professionals to specialize, and of course, include the introduction of color photography. We all have the option, however, to do the processing ourselves. Many dark room kits are available for beginners at moderate cost, and make great gifts for those intrigued enough to follow in the footsteps of the men and women who labored to make photography what it is today.

Black-and-white Photography
The history of black & white photography is essentially a significant part of the entire story of photography. Even after color film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its “classic” photographic look. he albumen process, first used more than 150 years ago, produces brown tones. In 1888, George Eastman of Rochester, New York introduced the public to the Kodak camera. “The original Kodak was a box camera, 3 1/4 X 3 3/4 X 6 1/2 inches with a fixed-focus lens of 27mm focal length. and took first photo from it.

Color Photo
Color photography was explored beginning in the mid-19th century. The first permanent color photograph was taken in 1861 using the three-color-separation principle first published by physicist James Clerk Maxwell in 1855. In color photography, light-sensitive chemicals or electronic sensors record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, Autochrome, the first commercially successful color process, was introduced by the Lumière brothers in 1907. Next the color photographs were subsequently accomplished in the early 20th century, including several as early as 1911. Color photography may form images as positive transparencies, which can be used in a slide projector. It has certainly come a long way since the days of James Clerk Maxwell, but it is positively astounding that the RGB color model are still utilized to this day. The foundation remains the same.
