  A lot of inventions are useful to people's life. In 1884, George Eastman invented a kind of film(膠卷)that fit into a small camera(照相機). Because the new film was easy to use, many people began to buy cameras. When they had used up their film, people returned their cameras to the factory. There, the film was developed, and pictures were printed. Then more film was put into the cameras, which were sent back to the owners, along with their pictures.

  Eastman's camera made it easy to take pictures. Today's cameras are even easier to use, and people can put in their own film.

  There are also many new jobs in the field of photography. One of the most important kinds of work is news reporting. Newspapers, magazines, and television all need pictures to tell their stories.
