Do you know who invented the camera and how it was invented? It was invented by Louis Daguerre in 1839.

The early camera was made of metal, glass and copper plates, which were very important for taking and keeping images. It was not easy to invent the camera. The inventor had difficulties in making the images clear and long-lasting, and reducing the exposure time. The invention of the camera has great meaning. It was responsible for the birth of modern photography and recording real history. Today, cameras are everywhere and help us record every wonderful moment. Homework Listen and read the text in 3a.
