Read the article carefully and finish the questions that follow:Documentary Photography              Documentary photography, or photojournalism, has helped create change in the world for over a century and a half. Now, more than ever, photographs tell truths about the world we live in. We can see these photographs in magazines and newspapers. We can view them in art galleries and museums. With the Internet and digital photography, images can instantly touch the hearts of people around the world. In fact, the word documentary comes from the Latin docere, which means “to teach.”              Would you be interested in seeing a photograph of someone who lived in the 1840s? It is possible. In 1839, two Frenchmen crated the first photograph image. It was called a daguerreotype. This method made a direct image on a silver plate. It was an exciting invention. But there was no way to make copies of these early images. They were used only for portraits. Not until 1851 was it possible to produce photo prints.              Many people consider this breakthrough as important as the printing press. Photography soon changed how people viewed history and time. It even changed how they thought about privacy. The demand for photographs became great. Photographers started traveling around the globe hunting for exotic, or strange and unusual, images.              Just a few years later, photography made its way to war. Roger Fenton was hired by the British government in 1855 to shoot photographs of the Crimean War in Europe. British war reporters had begun to send back frightening stories of British troops dying from bad medical care and cold weather. Criticism of the government increased. To cover up the facts, the government wanted Fenton to create scenes. Fenton produce over 350 pictures. He didn’t photograph any dead bodies or any actual battles. Instead, he shot photographs of groups of officers who looked proud, brave, and happy.              Not until 1862 did most people see true images of war. In that year, New York photograph Mathew Brady shocked Americans with photographs of dead Civil War soldiers. Brady was known for “getting the shot” on the battlefield. But he had a secret. He was nearly blind. Because he couldn’t see well, he hired 10 photographers who did the actual work on the battlefield. His team’s images were much more powerful than the posed portraits of soldiers that people had always seen. Brady and his team captured the feeling of dozens of Civil War battlefields just after the battles had ended. Even today, Brady’s images are a reminder of the war that nearly tore the United States apart.              Not only war, but other areas of life and society have been captured by photojournalists. In the 1879s, John Thomsonphotographed the lives of the poor working class in England. Jacob Riis, an immigrant to the U.S., photographed and wrote articles about the terrible living conditions of the poor in New York City. Lewis Hine traveled around the U.S. taking pictures of child laborers in mines and factories. During the Great Depression of the early 1900s, Dorothea Lange took pictures of farmers and farm workers to show the federal government how difficult life had become for these people.  These photographers used their pictures to help people and change society.Write 1, 2, or 3 in the box below.This article explainshow documentary photography developed.how photographs are made and printed.how to become a photojournalist.
