The document traces the history and development of cameras from 1727 to present day. It highlights several key innovations including the first photograph using silver nitrate in 1727, the first camera obscura in 1814, the Daguerreotype process in 1837 which reduced exposure time, Talbot's invention of photographic copying in 1841, the collodion process in 1851 which further reduced exposure time, gelatin dry plates in 1871 which allowed for delayed development, Eastman's roll film camera in 1888, Land's Polaroid camera in 1948 which developed photos instantly, color Polaroid film in 1963, the first digital camera in 1974 and the release of affordable camera phones and wireless cameras in the 1990s and 2012.

1. The Camera Timeline

2. 1727-The discovery that silver
nitrate changes
Johann Heinrich Schulze 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 obsucra 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.

5. 1841- Making multiple copies as
possible
William Henry Talbot developed the Calotype
process. This made it possible to make multiple
copies of the same picture

6. 1851- Taking pictures gets easier
With the new Collodion process, cameras only
needed a few seconds of light exposure to make
a picture.

7. 1871- Film 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- Invention of the roll-film camera
George Eastman invented the first roll-film
camera.

9. 1948- Polaroid camera
The Polaroid was invented by Edwin H. Land, it
allowed people to take a photo and have it
developed immediately, right from the camera.

10. 1963- Colour Polaroid
Polaroid came out with the first colored film.

11. 1974- First digital camera developed
The Sasson Company built the first digital
camera.

12. 1974- First Digital camera is marketed
Canon put out the first digital camera for the
public, which was later improved by Pixar.

13. 1980- First camcorder released
Sony put out the first consumer camcorder,
allowing people to record their memories in real
time.

14. 1990- First camera phones
The camera phone technology was first used in
Japan, but it quickly spread around the world.

15. 2001- Easy share camera
Kodak put out their Easy Share digital camera,
which made it easy to snap pictures and
download them to the computer.

16. 2012- Wireless cameras are developed
Kodak put out cameras that didn't have to be
connected to a computer in order to download
and share the pictures.
