The document outlines the key developments in camera technology from 1727 to 2012, including: Johann Heinrich Schulz's discovery in 1727 that silver nitrate changes color when exposed to light, paving the way for the first photographs. Joseph Niepce developed the first camera in 1814, though images faded quickly. Louis Daguerre invented the Daguerreotype process in 1837, reducing exposure time to 30 minutes and preventing images from fading. Later developments included making copies possible, shorter exposure times, dry plates allowing delayed development, roll film cameras, Polaroid cameras, color film, camcorders, digital cameras, camera phones, and wireless sharing capabilities.

Camera timeline
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 obscure is developed
Joseph Niepce developed the camera obscure 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.

2. 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 gelatine 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
The Polaroid allowed people to take a photo and have it developed
immediately, right from the camera.

3. 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.
1974 - The first digital camera is developed
The Sassoon 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.

4. 1990 - The first camera phones (1990's)
The camera phone technology was first
used in Japan, but it quickly 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.
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.
