The document outlines major developments in the history of photography from 1727 to 2001, including: - The discovery in 1727 that silver nitrate could capture images laid the foundation for photography. - Joseph Niepce developed the first photographic process using a camera obscura in 1814, though images faded quickly. - In 1837, Louis Daguerre invented the daguerreotype process which captured permanent images in only 30 minutes of exposure. - William Henry Talbot invented the calotype process in 1841, allowing multiple copies to be made from a single negative.

Timeline

2. 1727 - The discovery that silver nitrate changes
Johann Heinrich Schulz discovered that a substance called
silver nitrate would change colour when exposed to light.
This paved the way for the first pictures to be taken and
processed.

3. 1814 - The camera obscura is developed
Joseph Niepce developed the camera obscura and took
the first photo with it. It wasn't ideal, though, because it
took 8 hours of light exposure to make a picture, and the
picture faded with time.

4. 1837 - The Daguerreotype was invented
Louis Daguerre invented a new way to take pictures.
It only needed 30 minutes of light exposure, and the
image didn't fade with time. Louis Daguerre devised the
daguerreotype, the first successful form of permanent
photography.

5. 1841 - Making multiple copies possible
William Henry Talbot developed the c.
This made it possible to make multiple copies of the same
picture.
With the negative image, Fox Talbot
realised he could repeat the process of
printing from the negative.
Consequently, his process could make
any number of positive prints, unlike the
Daguerreotypes. He called this the
'calotype' and patented the process in
1841. The following year was rewarded
with a medal from the Royal Society for
his work.

6. 1851 - Taking pictures gets easier
Taking pictures gets easier
With the new Collodion process, cameras only needed a
few seconds of light exposure to make a picture.
The collodion process is an early photographic process,
invented by Frederick Scott Archer. It was introduced in
the 1850s and by the end of that decade it had almost
entirely replaced the first practical photographic process,
the daguerreotype.

7. 1871 - Film is made easier to handle
Up until this time pictures had to be developed
immediately after being taken. Richard Leach Maddox
invented the gelatin dry plate silver bromide process,
which made it possible to take a picture and develop it
later.

8. 1888 - The invention of the roll-film camera
George Eastman invented the first roll-film camera.

9. 1948 - The Polaroid camera is marketed
The Polaroid allowed people to take a photo and
have it developed immediately, right from the
camera.

10. 1963 - Colored film is introduced
Polaroid came out with the first colored film.

11. 1980 - The first consumer camcorder is released
Sony put out the first consumer camcorder,
allowing people to record their memories in real
time.

12. 1984 -The first digital camera is marketed
Canon put out the first digital camera for the public, which was later
improved by Pixar.

13. 1990 - The first camera phones (1990's)
The camera phone technology was first used in
Japan, but it quickly spread around the world.

14. 2001 - The Easy Share camera comes into play
Kodak put out their Easy Share
digital camera, which made it easy
to snap pictures and download
them to the computer.
