its invention, photography has always been linked with memory: photographs
recall family, friends and special moments, transcending time and
space to create an emotional bond between subject and viewer.
name "Photography" was first used by Sir John Herschel ,
who first used the term in 1839, the year the photographic process
became public. The word is derived from the Greek words for light
first successful picture was produced in June/July 1827 by Niépce,
using material that hardened on exposure to light. This picture required
an exposure of eight hours.
earliest paper negative we know of was produced in August 1835; it
depicts the now famous window at Lacock Abbey (see pic. below), taken
by William Henry Fox Talbot (1800-1877).
not all people welcomed this exciting invention; some pundits viewed
it in quite sinister terms. A newspaper report in the Leipzig City
wish to capture evanescent reflections is not only impossible... but
the mere desire alone, the will to do so, is blasphemy. God created
man in His own image, and no man- made machine may fix the image of
God. Is it possible that God should have abandoned His eternal principles,

artists saw in photography a threat to their livelihood, and some
even prophesied that painting would cease to exist.

of the Digital Camera
Digital camera technology evolved from the same technology that records
1951, the first video tape recorder (VTR) captured live images from
television cameras by converting the information into electrical impulses
(digital) and saving the information onto magnetic tape.
1956, VTR technology was perfected and in common use by the television
industry. Both television/video cameras and digital cameras use a
CCD (Charged Coupled Device) to sense light color and intensity.
the 1960s, NASA used digital signals to map the surface of the moon
(sending digital images back to earth). Computer technology was also
advancing at this time and NASA used computers to enhance the images
that the space probes were sending. Digital imaging was also used
by the USA in spy satellites.
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 which was the first commercial electronic
camera. Images were recorded onto a mini disc and then put into a
video reader that was connected to a television monitor or color printer.
However, the early Mavica cannot be considered a true digital camera
even though it started the digital camera revolution. It was a video
camera that took video freeze-frames.
the mid-1970s, Kodak has invented several solid-state image sensors
that "converted light to digital pictures" for professional
and home consumer use.
1986, Kodak scientists invented the world's first megapixel sensor,
capable of recording 1.4 million pixels that could produce a 5x7-inch
digital photo-quality print.
1987, Kodak released seven products for recording, storing, manipulating,
transmitting and printing electronic still video images.
Digital Memory Cards
1990, Kodak developed the Photo CD system and proposed "the first
worldwide standard for defining color in the digital environment of
computers and computer peripherals."
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.
first digital cameras for the 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 camera (March 28, 1995), the
Casio QV-11 (with LCD monitor, late 1995), and Sony's Cyber-Shot Digital
Still Camera (1996).
Kodak entered into an aggressive co-marketing campaign to promote
the DC40 and 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 which
allowed customers to produce Photo CD Discs and photographs, and add
digital images to documents. IBM collaborated with Kodak in making
an internet-based network image exchange. Hewlett-Packard was the
first company to make color inkjet printers that complemented the
new digital camera images.
marketing worked and today digital cameras are everywhere.
