     Photographs are everywhere. They decorate (装饰) the walls of homes and are used in stores for sales

of different goods. The news is filled with pictures of fires, floods, and special events. Photos record the

beauties of nature. They can also bring things close that are far away. Through photos, people can see wild

animals, cities in foreign lands, and even the stars in outer space. Photos also tell stories.

     Reporting the news through photos is called photojournalism. At times photojournalists tell their stories

through a single picture. At other times, they use a group of pictures to tell a story. Each picture is like a

chapter in a book, which can do more than record the facts. It can also be a strong force for social change.

     Jacob Riis was among the first photojournalists. He took pictures of parts of New York City where the

poor lived. Riis believed that poverty (贫穷) caused crime, and he used photos to help him prove his point.

A few years later, the photos of small children working in factories by Lewis Hine shocked the public. Hine's

pictures helped bring about laws to protect such children.

     Hundreds of pictures may have to be taken in order to get one or two really good photos. It takes science

to have the photo come out clearly and art to make a photo that has a good design and expresses feeling.

Photojournalists make an actual record of what they see. A photo, however, can be both a work of art and an

actual record. It can record an important event as a beautiful or exciting picture.

     As historical and artistic documents (文献), photos can become more important over time. Today

photojournalists still have their pictures appear in newspapers and magazines. They also publish (发表) them

in books and on the Internet.
