M4//S1 P4.1 Digital Photography Intro
While digital photography has only relatively recently become mainstream, the late 20th century saw many small developments leading to its creation. The history of digital photography as we know it began in the 1950s. In 1951, the first digital signals were saved to magnetic tape via the first video tape recorder. Six years later, in 1957, the first digital image was produced through a computer by Russell Kirsch Links to an external site.. It was an image of his son.
In 1981, Sony unveiled the first consumer camera to use a charge-coupled device for imaging, eliminating the need for film: the Sony Mavica Links to an external site.. While the Mavica saved images to disk, the images were displayed on television, and the camera was not fully digital.
The first digital camera to both record and save images in a digital format was the Fujix DS-1P created by Fujfilm in 1988.
In 1991, Kodak unveiled the DCS 100 Links to an external site., the first commercially available digital single lens reflex camera sold for retail price of $20,000.00
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. The word "photography" was created from the Greek roots φωτός (phōtós), genitive of φῶς (phōs), "light" and γραφή (graphé) "representation by means of lines" or "drawing", together meaning "drawing with light".
The first permanent photo was an image produced in 1822 by the French inventor Nicéphore Niépce. In 1826, he made the View from the Window at Le Gras, the earliest surviving photograph from nature.
