UNIT 9: PHOTOGRAPHY

TIMELINE

By josh brown

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.

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.

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.

1841

Making multiple copies possible

William Henry Talbot developed the Calotype process. This made it

possible to make multiple copies of the same picture

1851

Taking pictures gets easier

With the new Collodion process, cameras only needed a few seconds

of light exposure to make a picture.

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.

1888

The invention of the roll-film camera

George Eastman invented the first roll-film camera.

1948

The Polaroid camera is marketed

spread around the world.

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.

computer in order to download and share the pictures.
