Johann
H. Schulze, a German physicist, mixes
chalk, nitric acid, and silver in a flask;he
notices darkening on side of flask exposed to sunlight.
This accident created the first photo-sensitive compound. |

Carl
Scheele, a Swedish chemist, shows that the changes in the
color of the silver salts could be made permanent through
the use of chemicals |

A
French inventor, Nicéphore Niépce, produces
a permanent image by coating a metal plate with a light-sensitive
chemical and
exposing the plate to light for about eight hours. The photograph
was taken of a pigeon house and barn as seen from his window
in the summer of 1826 and
was made using a camera obscura and a sheet of pewter coated
with bitumen of Judea, an asphalt that when exposed to
light, hardened permanently. The photograph was
captured during an eight hour exposure, and took so much
time that the sun passed overhead, illuminating both sides
of the courtyard. |

Louis
Daguerre, a French inventor, develops the first practical
method of photography by placing a sheet of silver-coated
copper treated with crystals of iodine inside a camera
and
exposing it to an image for 5 to 40 minutes. Vapors from
heated mercury developed the image and sodium thiosulfate
made the
image permanent. Daguerre is awarded a state pension by the
French government in exchange for publication of methods
and the rights by other French citizens to use the Daguerreotype
process. |

A
British inventor, William H. Fox Talbot,
an English classical archaeologist, made paper sensitive
to light by bathing it
in a solution of salt and silver nitrate. The silver turned
dark when exposed to light and created a negative, which
could
be used to print positives on other sheets of light sensitive
paper. Talbot was the inventor of the negative/positive
photographic process, the precursor to most photographic
processes of the 19th and 20th centuries. |

Josef
M. Petzval, a Hungarian mathematician, develops lenses for
portrait and landscape photographs, which produce sharper
images and admit more light, thus reducing exposure time.

The
British photographer Frederick S. Archer develops a photographic
process using a glass plate coated with a mixture of silver
salts and an emulsion made of collodion. Because the collodion
had to remain moist during exposure and developing, photographers
had to process the pictures immediately. Wet plate collodion
photography was much cheaper than daguerreotypes, the negative/positive
process permitted unlimited reproductions, and the process
was published but not patented. |

The first color photograph, an additive projected image
of a tartan ribbon, is shown by James Clerk-Maxwell. Clerk-Maxwell
demonstrates a color photography system involving three black
and white photographs,
each taken through a red, green, or blue filter. The photos
were turned into lantern slides and projected in registration
with the same color filters. This is the "color separation" method.

Richard
L. Maddox, a British physician, invents the "dry-plate"
process, using an emulsion of gelatin, so that photographers
did not have to process the pictures immediately. By the late
1870s, exposure time had been reduced to 1/25th of a second.
Gelatin emulsion made it possible to produce prints that were
larger than the original negatives, allowing manufacturers
to reduce the size of cameras. |

Eadweard Muybridge makes a high-speed photographic
demonstration of a moving horse, airborne during a trot,
using a trip-wire system and settles the "do a horse's
four hooves ever leave the ground at once" bet among
rich San Franciscans. |

George
Eastman introduces and mass markets the lightweight, inexpensive
Kodak camera,
using film wound on rollers. It is the
first easy-to-use camera. This camera contains
a 20-foot roll of paper, enough for 100 2.5-inch diameter
circular pictures. |

Arthur Korn devises practical phototelegraphy
technology (reduction of photographic images to signals that
can be
transmitted by wire to other locations); Wire-Photos are
in wide use in Europe by 1910, and transmitted intercontinentally
by 1922. |

The first
digital still camera was a prototype (US patent 4,131,919)
developed by Eastman Kodak engineer Steven Sasson.
It was made up of some Motorola parts with a Kodak movie-camera
lens and some newly invented Fairchild CCD electronic sensors.The
resulting camera was the size of a large toaster and weighed
nearly 4kg. Black-and-white images were captured on a digital
cassette
tape, and viewing them required Sasson and his colleagues
to develop a special screen. |
