The document provides a history of photography from its origins with the camera obscura in ancient times through key developments and inventors up to the modern era of high speed photography and Eastman Kodak. It describes how the camera obscura was used by Aristotle and later Arab scholars to view the path of light. Louis Daguerre invented the daguerreotype process in the 1820s allowing photographs to be developed on silver plates. Joseph Nicéphore Niépce took the first permanent photograph in 1822. William Henry Fox Talbot invented the negative-positive process in 1839. James Clerk Maxwell created the first color photograph in 1861. High speed photography was pioneered by Eadweard Muybridge in

2. Camera Obscura
•
The camera obscura is a Latin Word for darkened room.
•
A guy called Aristotle noticed How light passing through a small hole
into a darkened room produces a image from outside on the
opposite wall back but upside down during a Partial eclipse sun
•
Then in the 10th Century ,Arabian Scholar Al Hassen used
•
The camera obscura to show how light travels in straight lines
In the 13th Century, the camera obscura was used by astronomers
•
to view the sun.

3. Louis Daguerre
A professional scene painter for the opera with an interest in lighting effects, Daguerre began
experimenting with the effects of light upon translucent paintings in the 1820s.
He regularly used a camera obscura as an aid to painting in perspective, and this led him think about ways
to keep the image still.
The French physicist created the daguerreotype, a process of transferring photographs onto silver-coated
copper plates.
According to writer Robert Leggat,Louis Daguerre made an important discovery by accident. In 1835, he
put an exposed plate in his chemical cupboard, and some days later found, to his surprise, that the latent
image had developed. Daguerre eventually concluded that this was due to the presence of mercury vapour
from a broken thermometer. This important discovery that a latent image could be developed made it
possible to reduce the exposure time from some eight hours to thirty minutes .

4. Joseph Nicéphore Niépce
Joseph Nicéphore Niépce made the
First ever picture in 1822 of Pope Pius VII
•
This picture is the only surviving picture of his earliest pictures

5. William Henry Fox Talbot
William made the first negative/positive
process in 1839 he refers this as photogenic
Drawing. This is used in modern photography

6. James Clerk Maxwell
James Clerk Maxwell was one of the greatest scientists who have ever lived, he
made the first permanent colour photograph in 1861.
He did ground breaking work with light,colour and imagery and by spliting light
into green,red and blue. He could reproduce any coloured imagery 50 years
before anyone else

7. High Speed Photography
The Society of Motion Picture and Television Engineers defined high-speed photography as any
set of photographs captured by a camera capable of 128 frames per second.
High-speed photography can be considered to be the opposite of
Time-lapse photography. The first is that the photograph itself may be taken in a way as to
appear to freeze the motion, especially to reduce motion blur.
The second is that a series of photographs may be taken at a high sampling frequency or frame
rate. The first requires a sensor with good sensitivity and either a very good shuttering system
or a very fast strobe light. The second requires some means of capturing successive frames,
either with a mechanical device or by moving data off electronic sensors very quickly.
The first practical application of high-speed photography was Eadweard Muybridge's 1878
investigation into whether horses' feet were actually all off the ground at once during a gallop

8. Eastman Kodak
Kodak was founded by George Eastman
In 1889.
George Eastman invented dry, transparent, and flexible, photographic film (or rolled photography film)
and the Kodak cameras that could use the new film.
Pre-loaded with enough film for 100 exposures, the Kodak camera could easily be carried and
handheld during its peration.
.After the film was exposed (all the shots taken), the whole camera was returned Kodak company in
Rochester, New York, where the film was developed, prints were made, new photographic film was
inserted, and then the camera and printswere returned to the customer.
