There are several ways to create a photograph. The most common photographs are made by using a camera. In many ways, a camera works like the human eye. Like the eye, the camera takes in rays of light reflected from a subject. It then focuses the rays into an image. Older cameras record the image on inserted film. Newer digital cameras record the image on an electronic storage device such as a memory card. Once the image is captured, it can be seen and enjoyed by many people.

When using a camera, the photographic process requires care and patience. Creating great printed photographs by using older cameras requires five steps: (1) finding a subject, (2) focusing on the subject, (3) exposing the film, (4) developing the film, and (5) producing the photograph. Many professional photographers do all five steps themselves. They use a room called a darkroom. It’s “dark” so that light doesn’t ruin the negatives.

Photography makes our lives richer in many ways. Through photographs we can learn about other parts of the world and see how people live. We can also imagine what life was like in other time periods since the mid-1800s, when the camera was invented. Special cameras can capture images in places most human beings can’t go, like distant planets or deep oceans. But, best of all, photographs remind us of the special people and special times in our lives. Millions of people use cameras to take pictures of their family, friends, and special celebrations. For them, the photographs they take are priceless.
