For centuries, people looked for ways to capture images. Early devices could project a scene, but they could not save it permanently. In the nineteenth century, inventors developed chemical methods that allowed light to create lasting pictures on prepared surfaces. Early photographs needed long exposure times, so people had to sit very still. Cameras gradually became smaller, faster and easier to use. Film photography later became popular, and digital cameras changed photography again. Today, billions of photographs are taken on phones every day.
