Johann Heinrich Schulz discovered in 1727 that silver nitrate would change color when exposed to light, paving the way for the first photographs. Joseph Niepce developed the camera obscura in 1814 and took the first photo, though it required 8 hours of exposure. In 1837, Louis Daguerre invented the daguerreotype process which reduced the exposure time to just 30 minutes and produced images that did not fade over time. William Henry Talbot then developed the calotype process in 1841, allowing for multiple copies of photographs.

2. THE DISCOVERY THAT SILVER
NITRATE CHANGES
Date: 1727
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. THE CAMERA OBSCURA IS
DEVELOPED
Date: 1814
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. THE DAGUERREOTYPE WAS
INVENTED
Date:1837
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. MAKING MULTIPLE COPIES POSSIBLE
Date:1841
William Henry Talbot developed the Calotype process. This made it possible to
make multiple copies of the same picture.

6. TAKING PICTURES GETS EASIER
Date: 1851
With the new Collodion process, cameras only
needed a few seconds of light exposure to make a
picture.

7. FILM IS MADE EASIER TO HANDLE
Date: 1871
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. THE INVENTION OF THE ROLL-FILM
CAMERA
Date: 1888
George Eastman invented the first roll-film camera.

9. THE POLAROID CAMERA IS
MARKETED
Date: 1948
The Polaroid allowed people to take a photo and
have it developed immediately, right from the
camera.

10. COLOURED FILM IS INTRODUCED
Date: 1963
Polaroid came out with the first coloured film.

11. THE FIRST DIGITAL CAMERA IS
DEVELOPED
Date:1974
The Sasson Company built the first digital camera.

12. Date:1980
Sony put out the first consumer camcorder, allowing
people to record their memories in real time.

13. THE FIRST DIGITAL CAMERA IS
MARKETED
Date: 1984
Canon put out the first digital camera for the public,
which was later improved by Pixar.

14. THE FIRST CAMERA PHONES
Date: 1990
The camera phone technology was first used in
Japan, but it quickly spread around the world.

15. THE EASY SHARE CAMERA COMES
INTO PLAY
Date: 2001
Kodak put out their Easy Share digital camera, which
made it easy to snap pictures and download them to
the computer.

16. WIRELESS CAMERAS ARE DEVELOPED
Date: 2012
Kodak put out cameras that didn't have to be
connected to a computer in order to download and
share the pictures.
