Photography is the process of making pictures by means of the action of light. Light reflected from a subject forms an image of that subject on a light-sensitive device or material. Usually, but not always, the device or material is inside a camera. The image formed by the light is then digitally or chemically processed into a photograph. The word photography comes from Greek words meaning to write or draw with light.
Photography enriches our lives in many ways. From photographs, we can learn about people in other parts of the world. Photographs show us scenes from such historic events as the American Civil War (1861-1865) and the first human moon landing in 1969. Photographs also remind us of special people and important events in our own lives. Millions of people throughout the world take pictures of their family, friends, vacations, and celebrations.
Special cameras can capture images in places where human beings cannot go
