The invention of the camera goes far into the past . In the 1500s , men were experimenting with cameras that made images . But it was not until the early 1800s that man found a way to make the pictures permanent . Even then , photography was a new field . Most families had their pictures taken by a photographer . People did not own cameras because taking pictures and developing the film were too difficult . In 1884, George Eastman changed photography by inventing a kind of film that fit into a small camera . 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 . Photography has become a growing hobby . There are also many new jobs in the field of photography . One of the most important kinds of work is in news reporting . Newspapers, magazines , and television all need pictures to tell their stories . Photographers aid scientists by taking pictures through microscopes and telescopes . Deep-sea divers take pictures of ocean plants and animals , while astronauts take their cameras into space . Man finds new uses for the camera every day . 相机的发明可以追溯到很早以前。在16世纪，人们就在进行有关摄像的试验。但是直到19世纪早期，人们才找到了使之成像的方法。在那个时候，照相是件新鲜事物。多数家庭请摄像师来照相，而自己不会买相机，因为照相、冲印太难了。 在1884年，乔治-艾斯特曼发明了一种可以放进小型相机中的胶片。由于这种胶片的使用改进了摄像技术，很多人开始买相机了。当他们用完胶片时，就把相机送回厂家，在那里冲印照片。然后，厂家会把新的胶卷装进相机，连洗好的照片一起返还给顾客。 艾斯特曼的相机使摄像变得简单方便了。今天的相机更是简单好用，人们自己就能换胶片，摄像已经成了越来越多人的一种爱好。 在拍摄领域也产生了许多新的职业。其中最重要的职业之一就是新闻记者。报纸，杂志和电视台都照片来报道消息。科学家通过摄像师的帮助可以由显微镜和望远镜中得到图片，深海潜水员可以拍到海洋中的动物和植物，而宇航员将他们的相机带进了太空。人们每天都在发现相机新的用途。 本文来源：https://www.wddqw.com/doc/9be3482b852458fb770b5698.html
