Transcript
The earliest stage of the camera’s invention was the camera obscura, a device used by ancient Chinese and Greek civilizations. The camera obscura was a dark room that let in a small amount of light through a hole and projected a mirror image of an object outside. In 1826, Joseph Nicéphore Niépce created the first permanent photograph by using light-sensitive substances inside a camera obscura. By the late 1800s, inventor Louis Daguerre had created a camera that could take photographs on silver sheets. These photographs were called daguerreotypes. However, they were expensive and not widely available. Photography became more accessible in the 20th century, when anyone could buy low-cost film cameras. Today, digital cameras work by using electrical signals to gather and store information about the light they detect.
