1727The discovery that silver nitrate changes

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

1814The 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.

1837The 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.

1841Making multiple copies possible

William Henry Talbot developed the Calotype process. This made it possible to make multiple copies of the same picture.

1851Taking pictures gets easier

With the new Collodion process, cameras only needed a few seconds of light exposure to make a picture.

1871Film 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.

1888The invention of the roll-film camera

George Eastman invented the first roll-film camera.

1948The Polaroid camera is marketed

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

The camera phone technology was first used in Japan, but it quickly spread around the world.

2001The 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.

2012Wireless 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.
