The 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.

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.

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.

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

Leach Maddox invented the gelatin dry plate silver bromide process, which made it
possible to take a picture and develop it later.
