The pictures illustrate how the camera developed since it was invented in 1839 until the year 2000.
Four models are shown in the diagrams. The earliest model, the Daguerrotype, was invented in 1839. This camera, which was made of wood, was 36 centimetres in length and consisted of three box-shaped sections. It had a brass lens at the front. Almost fifty years later, the Kodak No.1 appeared. This cube-shaped model was less than half the size of the Daguerrotype and was made of metal instead of wood. In 1925, the Leica 1 came onto the market. It was much narrower than its predecessor and also had numerous function buttons along the top. Finally, in 2000, the Digital camera was introduced. Made of plastic, this camera was only a fraction of the size of the first camera, and it also had more features than all of the previous models. These features included a zoom lens and access to the Internet.
Overall, the camera became smaller and more complex during the nineteenth and twentieth centuries.
