The document traces important developments in camera technology from the 18th century to present day, including: - In the 18th century, silver nitrate was discovered to change color with light exposure, allowing the first photographs to be taken and processed. - Throughout the 19th century, techniques like the daguerreotype, calotype, and collodion process improved photograph exposure times from hours to seconds. - In the late 19th century, roll film and dry plates made photography more portable and convenient. - Major 20th century developments included Polaroid, color film, camcorders, digital cameras, camera phones, and easy to use share cameras.

1. 1727 The discovery that silver nitrate changes
Johann Heinrich Schulz discovered that a substance called silver nitrate would change colour when exposed to li
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.

2. 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.

3. 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.

4. 1888 The invention of the roll-film camera
George Eastman invented the first roll-film camera.
1948 The Polaroid camera is marketed
The Polaroid allowed people to take a photo and have it developed immediately, right from the camera.

5. 1963 Coloured film is introduced
Polaroid came out with the first coloured film.
1980 The first consumer camcorder is released
Sony put out the first consumer camcorder, allowing people to record their memories in real time.

6. 1974 The first digital camera is developed
The Sasson Company built the first digital camera.
1984 The first digital camera is marketed
Canon put out the first digital camera for the public, which was later improved by Pixar.
1990 The first camera phones (1990's)

7. The camera phone technology was first used in Japan, but it quickly s
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.
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.
