For most of the twentieth century, all photographers had at their disposal was cameras and film to make new images. With the advent of magnetic videotape in the 1980s, so the technology – and the use of it - began to change, however. Soon the first digital SLR cameras were being made which created files of images rather than pictures that needed to be developed from films. Eventually, such digital cameras became so light, portable and convenient to use that they were installed into smartphones. Nowadays, virtually everyone has a highly sophisticated camera in their pocket they can use to shoot stills and videos and to share them instantly.
