The diagram show how the camera has evolved from its early beginnings in 1839 until a more recent version in 2000.
In 1839 the Daguerrotype camera was invented. This was a wooden structure in the shape of a square with a length of 36cm and a brass lens. The Kodak no. 1 came out about half a century later. It was approximately half the size of the Daguerrotype, in the shape of a square and made of metal.
The 1925 Leica 1 introduced a new design to the camera. It was 2cm shorter than its predecessor but still made of metal. This camera had an external lens and buttons on top to operate it. The 2000 digital camera became sleek, measuring 8cm in length. It was lighter, being made of plastic. In keeping with advances in technology, the added features of this camera include a zoom lens, flash, LCD screen and internet connection to transfer photos onto a computer.
In the past, cameras were bulky and heavy, using wood and metal. Modern cameras are smaller, lighter and have many more features and options for storing and viewing photos.
