Camera 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 wouldbe seen on the opposite wall.� Light travels in a straight line and

when some of the rays reflectedfrom a bright subject pass througha small hole in thin material they

do not scatter but cross andreform as an upside down imageon a flat surface held parallel tothe hole (Wilgus)

focus is achieved by sliding the inner section of the box in and out. The image projected by thelens is focused by a mirror up to a glass under thehood where it can be traced on tissue (Wilgus)

Professor J. Schulze� Accidental creation of the

first photo-sensitivecompound by mixing nitric acid,

silver, and chalk in a flask.� Dealt with exposure, the

chemicals in the glass jar changed color when facing thesun

� Determines that light is thecause of the change

Thomas Wedgwood� 1802- presented a paper about

´method of copying paintingsupon glass, and of making profiles

by the agency of light uponnitrate of silver.µ� Put an object on paper coated

with silver nitrate and exposed itto natural light then preserve it ina dark room.

� Never developed a fix, imagescould only be viewed incandlelight.

Louis Daguerre� Began work as an apprentice

architect� was a painter, physicist, and the

inventor of Daguerreotype² 1837- he figured out how to get the image to stick,exposed directly onto amirror-polished surface of silver, which has first beenexposed to iodine vapor

² made public in 1839² Made his idea available to the

public at no fee (Loomis)² accepted into the Academy

of Sciences

.

Henry Fox Talbot� Popularized photography

(Loomis)� Discovered the latent image

� ´The Pencil of Natureµ was thefirst book with photographs,published by Talbot

� Calotype process, negativesmade

�Phologlyphy process, Photoetching

Latent Image

� Latent image was discovered in 1841. It is aninvisible image consisting of electrical charges.

� ´In photography a latent image is formed whenlight acts on a photographic emulsion (the

mixture of two unmixed substances). This imageis invisible until the emulsion is developed using photographic developersµ (J.W. Mitchell).

Pinhole Photography

� Pinhole images are softerthan pictures made with alens. The images have

nearly infinite depth of field.� Cameras have been made

of seashells; many havebeen made of oatmealboxes, coke cans or cookiecontainers (Grepstad).

� In fourth century BC,Aristotle makes notes in hiswork Problems on pinholeimage formation.

� The pinhole was mainlyused later for scientificpurposes in astronomy as a

drawing aid for artists andamateur painters.

� Sir David Brewster was oneof the first to make pinholephotographs in the 1850s.

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).

Joseph Nicephore Niepce� French Chemist who originated a

process of photography.� In 1816 he created the first

negative image called a ´retinasµ� In 1826 he produced the first

known photograph called theheliograph using a form of asphalton a pewter plate

� 1828 he returned to his work and

discovered a new method that letto super quality images� He worked with Louis Daguerre

until his death

The 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 andPresentation: Tyler



Johannes 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
