||
Used
silver-plated sheet of copper |
||
Placed
silver side down over box containing iodine |
||

||
| No image visible afterwards | ||
Exposed
plate to fumes from heated mercury |
||
| Image became visible | ||
Plate
bathed in strong solution of table salt |

Sir John Frederick William Herschel provides the final element necessary when he discovers that hyposulphite of soda will arrest the action of light, making photographic images permanent |
Julia Margaret Cameron. Sir John Frederick William Herschel. 1867. |
hyposulphite of soda acts as a fixer, removing unexposed silver halide, and therefore preventing any further reaction of the silver salts |
|
Later coins the term photography = light writing |
|
and applies the terms "positive" and "negative" |

Hippolyte Bayard. Plaster Casts. c. 1839. |
1838 | Daguerre hires Count Francois Arago, Secretary of the Academy of Sciences, to promote invention and secure copyright from government | |

| Exposes paper with silver chloride emulsion to light | |||
| Soaks paper in potassium iodide | |||
| Exposes paper in obscura about 12 minutes | |||
| Washes paper in bath of hyposulphite of soda | |||
| Bayard shows examples of prints to Count Arago | |||
| Arago pressures Bayard not to publish results of his experiments | |||
| January 9, 1839 | Arago announces Daguerre's process to a joint session of the Academy of Science and the Academy of Fine Art | |
| August 19, 1839 | Daguerre's process is announced to the public and Daguerre receives French patent on his process | |
| Daguerre receives lifetime pension from French government | ||
| Daguerre applies for English patent on the process | ||
| Daguerre claims full credit for the invention (Niepce goes unrecognized for years) | ||

"The
corpse you see is that of M. Bayard
The Academy, the King and
all those who have seen his pictures admired them, just as you do
This has brought him prestige, but not a penny. The government, which
has supported M. Daguerre more than is necessary, declared it could
do nothing for M. Bayard, and the unhappy man drowned himself
he
has been at the morgue for several days, and no one has recognized him.
Ladies and gentlemen, you'd better pass along for fear of offending
your sense of smell, for as you can observe, the face and hands of the
gentleman are beginning to decay." - Hippolyte Bayard |

daguerreotype, "the mirror with a memory." - Oliver Wendell Holmes |
Properties of the daguerreotype: |
Mirror view of the original scene |
Shiny, mirror-like surface |
Very delicate, one-of-a-kind direct positive image |
Daguerreotype
drawbacks : |
Long exposure
time |
Beyond the average person's means |
Cameras
were large and cumbersome |

By the end of
1840 three major improvements made: |
Cameras manufactured with better quality lens |
More light-sensitive
plates developed |
Enriched
tones of daguerreotype image with gilding |

Construction of a daguerreotype: hinged, velvet-lined case, plate, frame, matte, and glass.

The blossoming popularity and accessibility of the daguerreotype greatly influenced the emergence of new classes of image makers, which then encouraged the development of new classes of images... |

Talbot produced the first successful negative on paper in 1835 |
Calotype process: |
Soaked paper in a solution of sodium chloride, then a solution of silver nitrate |
Repeated process several times to create a dense concentration of chemicals |
Exposed wet sheet of iodized paper to light (cutting exposure time from 1 hour to 10 minutes) |
Image fixed with either potassium iodide or sodium chloride |
In the following years, Talbot discovered that an invisible, "latent image" could be developed with gallic acid |
Began coating paper with wax to make it more translucent |
Negative was contact printed onto another sheet of sesnsitized paper |
the calotype
established a negative/ positive printmaking system |
|
1. Negative
image produced by exposing light-sensitive paper |
|
2. Positive
image produced by contact printing onto another piece of paper |
