A power point on different photography techniques and camera through history

1. 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.

2. 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.

3. 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.

4. 1841 Making multiple copies
possible
• William Henry Talbot developed the Calotype
process. This made it possible to make
multiple copies of the same picture.

5. 1851 Taking pictures gets easier
• With the new Collodion process, cameras only
needed a few seconds of light exposure to
make a picture.

6. 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.

7. 1888 The invention of the roll-film
camera
• George Eastman invented the first roll-film
camera.

8. 1948 The Polaroid camera is
marketed
• The Polaroid allowed people to take a photo
and have it developed immediately, right from
the camera

9. 1963 Coloured film is introduced
• Polaroid came out with the first coloured film

10. 1980 The first consumer camcorder
is released
• Sony put out the first consumer camcorder,
allowing people to record their memories in
real time.

11. 1974 The first digital camera is
developed
• The Sasson Company built the first digital
camera

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.

15. 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.
