- In 1727, Johann Heinrich Schulz discovered that silver nitrate could capture images when exposed to light, paving the way for the first photographs. - In 1814, Joseph Niepce developed the camera obscura but images faded quickly and exposure times were long. - In 1837, Louis Daguerre invented the Daguerreotype process which dramatically reduced exposure times and prevented images from fading.

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

3. 1814
▪ 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
▪ 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
▪ 1841
▪ Making multiple copies possible
William Henry Talbot developed the Calotype process. This made it possible to
make multiple copies of the same picture.

6. 1851
▪ 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
▪ 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
▪ 1888
▪ The invention of the roll-film camera
George Eastman invented the first roll-film camera.
