There you are with that teddy bear you had when you were 2 years old. Someone took your picture. The camera “captured” your image.
To make a photograph, you look through a tiny window called a viewfinder to see what will be in the picture. Next, you press a button that controls a small opening called a shutter. Most of the time, the shutter is closed. When you take a picture, the shutter opens for just a small part of a second.
Behind the shutter is a lens, which bends light rays and makes them focus, or come together. The light is captured on film, or if you are using a digital camera, on an electronic chip. The light “prints” a picture on the film or chip.
When you use up a roll of film, you take it to a store to be developed. Then you will have pictures you can keep.
A digital camera stores your photographs on the electronic chip. You can view pictures from a digital camera on a computer or television screen. You can use your computer to send the pictures to your friends, or you can print them out.
