2Camera Obscura
- Latin for Dark room
- A dark box or room with a hole in one end. If the
hole is small enough, an inverted image would be
seen on the opposite wall. - Light travels in a straight line and when some of
the rays reflected from a bright subject pass
through a small hole in thin material they do not
scatter but cross and reform as an upside down
image on a flat surface held parallel to the hole
(Wilgus)
focus is achieved by sliding the inner section of
the box in and out. The image projected by the
lens is focused by a mirror up to a glass under
the hood where it can be traced on tissue (Wilgus)

3Professor J. Schulze
- Accidental creation of the first photo-sensitive
compound by mixing nitric acid, silver, and chalk
in a flask. - Dealt with exposure, the chemicals in the glass
jar changed color when facing the sun - Determines that light is the cause of the change
Info, presented by, and slide Joe
4Thomas Wedgwood
- 1802- presented a paper about method of copying
paintings upon glass, and of making profiles by
the agency of light upon nitrate of silver. - Put an object on paper coated with silver nitrate
and exposed it to natural light then preserve it
in a dark room. - Never developed a fix, images could only be
viewed in candlelight.

5Louis Daguerre
- Began work as an apprentice architect
- was a painter, physicist, and the inventor of
Daguerreotype - 1837- he figured out how to get the image to
stick, exposed directly onto a mirror-polished
surface of silver, which has first been exposed
to iodine vapor - made public in 1839
- Made his idea available to the public at no fee
(Loomis) - accepted into the Academy of Sciences
.

6 Henry Fox Talbot
- Popularized photography (Loomis)
- Discovered the latent image
- The Pencil of Nature was the first book with
photographs, published by Talbot - Calotype process, negatives made
- Phologlyphy process, Photo etching

7Latent Image
- Latent image was discovered in 1841. It is an
invisible image consisting of electrical charges. - In photography a latent image is formed when
light acts on a photographic emulsion (the
mixture of two unmixed substances). This image is
invisible until the emulsion is developed using
photographic developers (J.W. Mitchell).

8Pinhole Photography
Pinhole photography is lens-less photography. A
tiny hole replaces the lens. Light passes through
the hole an image is formed in the camera
(Grepstad).
- Pinhole images are softer than pictures made with
a lens. The images have nearly infinite depth of
field. - Cameras have been made of seashells many have
been made of oatmeal boxes, coke cans or cookie
containers (Grepstad). - In fourth century BC, Aristotle makes notes in
his work Problems on pinhole image formation.
- The pinhole was mainly used later for scientific
purposes in astronomy as a drawing aid for
artists and amateur painters. - Sir David Brewster was one of the first to make
pinhole photographs in the 1850s.

9Joseph Nicephore Niepce
- French Chemist who originated a process of
photography. - In 1816 he created the first negative image
called a retinas - In 1826 he produced the first known photograph
called the heliograph using a form of asphalt on
a pewter plate - 1828 he returned to his work and discovered a new
method that let to super quality images - He worked with Louis Daguerre until his death

10The First Photograph
- Taken by Joseph Nicephore Niepce in 1826
- eight hour exposure
- Taken with camera obscura
- The photo was unrecognized for almost a half a
century - now one of the worlds rarest artifacts.
Info Slide and Presentation Tyler
11Johannes Kepler
- Johannes wrote the novel "Astronomia Pars Optica
which explained how to investigate the formation
of pictures with a pinhole camera (Johannes
Kepler (1571-1630)). - He gave the modern explanation of how the eye
works - His theories helped to modernize the pinhole
