A Brief History of Light & Photography by Rick DobleRick Doble
This fully illustrated 23 page paper traces the history of photography and our understanding of light from prehistoric times to the present day and also speculates about the future. From Aristotle to Einstein the camera is much older than most realize. Because photography can record fine detail and freeze a moment of the past, it has also transformed our modern understanding of time and also provided a record of the past which was previously unavailable.
A short description of the history before photography was officially invented. Why was there a need for photography? What were the substitutes until the first inventions? What were the first photographic inventions? And what did they lead to?

Optical illusions have appealed to the mind of spectators throughout
history, and have had great impact when combined with architectural
elements. Illusionary methods have been used by artists and architects
since antiquity, but only during the Renaissance were they scientifically
analysed to produce the techniques of perspective, anamorphosis,
and their integration with trompe l’oeil. This paper is a study of these
methods employed by artists and architects, focusing on the invention
and evolution of the technique of anamorphosis from its birth during
the Italian Renaissance. By analysing a compilation of early and
contemporary cases of architectural illusionism in two and three
dimensions, the methods used to manipulate observers’ perceptions
are explored in detail. By reintroducing these techniques of the past
into contemporary practice they can prove very beneficial by
producing enhancing spaces when spatial or economic restraints must
be overcomeUccello, Mantegna, masschio, and Leonardo da Vince

Week 1
Visual Culture in the Western World
The Idea of Cinema
-Fascination with images can be traced back to
Plato (The Republic) in the parable of “The Cave”
Plato raises the danger of being
complacent with the illusion of the image
The dangers of an uncritical
understanding of the image
-The period of Enlightenment:
scientific studies and machinations are developed
to “capture, project and record images.
-17th century:
Athanasius Kircher (1601-1680)
developed the “catoptric lamp.”
German-born Jesuit priest and scientist whose
book Ars magna lucis et umbrae diagramed the
outlines for his reflecting optic machine.
Did not invent the “magic lantern”
He projected and reflected images on the wall
Encouraged scientific explanation to his spectators
so as to demythify images as some sort of magic
or ghostly apparition.
He emphasised that these images were not magic,
but “art.”
The Magic Lantern—17th Century
2
1659—Christiaan Huygens develops the “lanterne
magique”
1664—Thomas Walgensten developed a similar
apparatus in Paris
Unlike Kircher who used sunlight to reflect the
image Huygens and Walgensten used an artificial
light source
Walgensten traveled through Europe with the
“lanterne magique” (Lyons, Rome, and
Copenhagen)
The people who saw the lanterne magique were
initially royalty in these cities
By the end of the century the lantern shows were
exhibited in more popular culture venues such as
fairs and carnivals
18th and 19th CENTURIES
1740— X. Theodore Barber demonstrates the
“Magick Lanthorn” in Philadelphia, New York, and
Boston.
Venues such as private homes and coffee houses
were the favored sites for these exhibitions.
France, however, was where these lantern shows
first gained commercial popularity at the beginning
of the 19th century.

Etienne Gaspars Robertson
“Fantasmagorie” capitalized on superstitions and
religious fears
Invoked the “spirits” of Rousseau and Voltaire
It was a theater of apparitions.
Unlike Kirhcer, Robertson did not tell his audiences
that the “Fantasmagorie” was a technological
spectacle
Like contemporary theater and film, Robertson
maintained the illusion of the image
-It was an extremely complicated production to
put on - images size and intensity of light had to
be continuously managed
The Fantasmagorie was internationally popular.
Each traveling show was uniquely packaged
usually attended by an adult urban middle-class
audience.
1803—Barber presented the French Fantasmagoria
in New York
1803—Showmen Bologna and Thomlinson
exhibited the Fantasmagoria in London
Americans saw the ghost of Benjamin Franklin
and exotic figures like the “Egyptian Pygmy Doll”

There was sound with these presentations—
ghost’s voices, music
Ticket prices were approximately US$1.
