Canon PowerShot S230 is latest model and released 2002 which is max resolution 2048.Though there are many types of cameras, all include five indispensable components: (1) the camera box, which holds and protects the sensitive film from all light except that entering through the lens; (2) film, on which the image is recorded, a light-sensitive strip usually wound on a spool, either manually or automatically, as successive pictures are taken; (3) the light control, consisting of an aperture or diaphragm and a shutter, both often adjustable; (4) the lens, which focuses the light rays from the subject onto the film, creating the image, and which is usually adjustable by moving forward or back, changing the focus; and (5) the viewing system, which may be separate from the lens system (usually above it) or may operate through it by means of a mirror.
the dimensions of Canon PowerShot S230 is 87The earliest camera was the camera obscura, which was adapted to making a permanent image by Joseph Nicéphore Niepce and Louis-Jacques-Mandé Daguerre of France in the 1820s and 1830s. Many improvements followed in the 19th century, notably flexible film, developed and printed outside the camera. In the 20th century a variety of cameras was developed for many different purposes, including aerial photography, document copying, and scientific research.
In xerography, a light exposure is made upon a uniformly charged metal plate, the selenium coating of which then selectively destroys the charge in conformity with the original. The image is made visible by dusting the plate with an oppositely charged pigmented powder; it is then transferred to paper electrostatically and fused with heat. Modern xerographic machines use a continuously rotating metal drum on which the various steps—charging, exposing, developing, and transferring—are carried out continuously.
A proprietary process known Canon PowerShot S230as Electrofax employs a photographic paper coated with a dielectric layer; the entire charging, exposure, and development process is thus effected directly on the paper itself.
The company was incorporated in 1901 as the successor to a business established in Rochester in 1880 by George Eastman, who perfected the newly developed method of making photographic dry plates. Before 1880, photographers had to coat a plate with fresh, wet chemicals each time they wanted to take a picture. Eastman developed a machine that mechanically produced dry, precoated plates, and he set up the company that later would become amazon.com/mytv Eastman Kodak to sell his plates.
Four years later Eastman introduced roll film, and in 1888 he introduced the Kodak camera, install turbotax with license codethe first camera that was simple and portable enough to be used by large numbers of amateur photographers. The camera was sold with film sealed inside, and the whole unit was mailed back to Rochester for film processing and replacement. In 1900 Eastman introduced the less-expensive Brownie, a simple box camera with a removable film container, so that the whole unit no longer needed to be sent back to the plant.
In following years the company continued to produce innovations for amazon.com/mytvthe amateur photographer. Kodak was the first to make home-movie equipment and an easy-to-use colour slide film, Kodachrome. In the 1960s the company introduced the Instamatic series of still and movie cameras, all of which used cartridge-loaded film. The Disc camera series, introduced in 1982, was a technologically advanced group of cameras that could automatically activate the use of the flash, if necessary, in addition to adjusting the focus and advancing the film. In 1984 the company entered the video market by introducing an 8-millimetre video camera system and videocassette tapes.
By the early 21st century, facing significant declines in the consumer market for cameras and other products related to film photography, Kodak placed new emphasis on digital photography products. The company remained a leading supplier of photographic films, papers, and chemicals for professional photographers and also manufactured motion-picture film, single-use and other consumer digital cameras, aerial surveillance films, install turbotax with license codeand equipment for the graphic communications industry into the 21st century. Kodak filed for bankruptcy in January 2012 and announced soon after that it would no longer manufacture digital cameras and some other digital imaging products.
