History of Digital Cameras and Photography


Camera Obscura - 1490. Leonardo da Vinci wrote the first detailed description of the camera obscura in his Atlantic Codex, a collection of 1286 photographyof photographyHistory History page images and text. The principle of the camera obscura involves hitting a hole in a dark box and put a piece of light-sensitive material on the other side so as to provide photo. The first image of the pinhole camera obscura is a drawing by Gemma Frisus' De Radio, astronomer (above photo on the left). He used a pinhole in a dark room to study solar eclipse 1544.

FIRST PERMANENT CAMERA photo - 1825-1826. history of photography was recently re-written after the discovery of what is now considered the world's oldest photo. Image, a reproduction 17th-century print Netherlands, preceded by one year earlier heliogravure France Nicéphore Niépce about the look of the window at Le Gras, considered until now as the earliest surviving photographic images.

In the early 1800s, Joseph Nicéphore Niepce experimented with lithography at his home near Chalon, France. Nicéphore explored varnish sensitive to light, trying to find a coating that will record images after exposure to light. In 1816, he took a picture with the camera and paper sensitized with silver chloride. He had some success, but was not satisfied because the image is inverted (negative) and can not be made permanent. He has tried to produce a positive print, but can not do it. He found that the nitric acid helps to maintain the picture for a while, but it will not prevent the eventual fading. Niepce breakthrough came in 1822 when he made a permanent image using a camera obscura. After showing coated tin plate to the camera image, it uses steam from heated iodine crystals to darken the silver and improve contrast. This method was later inspired Louis Daguerre's successful mercury vapor development process. Within a few years the two inventors would be partners. Niepce able to produce a copy of an engraving by passing light through the original photo into a piece of glass coated with bitumen of Judea, a type of asphalt. The light hardens bitumen of Judea, so when Niepce washed dishes with only the unexposed solvent removed, leaving a permanent image on the plate. He said the process is "heliography" or sun-write. He made heliographs lot over the next few years and continue to strive to produce a permanent camera image. In 1825, he succeeded.

Oldest known photograph, 1825 and 1826.

The first image is a reproduction of a 17th century engraving showing a man leading a horse Netherlands. This photo was sold at Sotheby's in Paris on March 21, 2002, to the National Library of France for $ 443,000 (£ 330,000).

both the world's oldest known still image camera, asphalt on the tin, is a view taken from Niepce's second-story window. exposure took about eight hours. The third picture is reportedly also made in 1826.

The first digital camera

Digital camera technology is directly related to and evolved from the same technology that recorded television images. In 1951, the first video tape recorder (VTR) photo taken directly from television cameras by converting the information into electrical impulses (digital) and records information on magnetic tape. Bing Crosby laboratories (the research team funded by Crosby and headed by engineer John Mullin) created the first early VTR and by 1956, VTR technology perfected (the VR1000 invented by Charles P. Ginsburg and the Ampex Corporation), and are commonly used by the television industry. Both cameras TV / video and digital cameras use CCD (Charged Coupled Device) sense of color and light intensity.

During the 1960s, NASA converted from using analog to digital signals with their spacecraft to map the surface of the moon (sending digital images back to earth). Computer technology was also developed at this time and NASA used computers to enhance images that the space probes sent.

Digital imaging also had another government use at that time was a spy satellite. The government uses digital technology to help advance the science of digital imaging, a significant contribution, however, the private sector also made. Texas Instruments patented a film-less electronic camera in 1972, the first to do so. In August, 1981, Sony released the Sony Mavica electronic still camera, the camera is the first commercial electronic camera. Images are recorded onto a mini disc and then put into a video reader that is connected to a television monitor or color printer. However, the early Mavica can not be considered a true digital camera even though it started the digital camera revolution. It is a video camera that took video freeze-frames.

Since the mid-1970s, Kodak has created several solid-state image sensors that "converted light to digital pictures" for professional and home consumer. In 1986, Kodak scientists discovered the world's first megapixel sensor, capable of recording 1.4 million pixels that could produce prints 5x7 inch photo-quality digital. In 1987, Kodak released seven products for recording, storing, manipulating, transmitting and printing electronic still video images. In 1990, Kodak developed the Photo CD system and proposed "first-world standards to specify the color in the digital environment of computers and computer peripherals." In 1991, Kodak released the first professional digital camera system (DCS), aimed at photojournalists. It was a Nikon F-3 camera equipped by Kodak with a 1.3 megapixel sensor.

Digital Camera first consumer-level market that worked with a home computer via a serial cable were the Apple QuickTake 100 camera (February 17, 1994), the Kodak DC40 digital cameracamera The first (March 28, 1995), the Casio QV-11 (with LCD monitor, late 1995), and the Sony Cyber-Shot Digital Still Camera (1996).

However, Kodak entered into a co-marketing campaign to promote the DC40 and aggressively to help introduce the idea of digital photography to the public. Kinko's and Microsoft both collaborated with Kodak to create digital image-making software workstations and kiosks that allow customers to produce Photo CD Discs and photographs, and add digital images to documents. IBM is working with Kodak in making an internet-based network image exchange. Hewlett-Packard was the first company to make color inkjet printer equipped with a new digital camera pictures.
