People have always made pictures. The first pictures were prehistoric cave painting, and painting is still a popular way to make pictures. However, technological developments in the past 150 years have given us new ways to show our world in pictures. Different kinds of cameras take still photographs and record moving images on film or video. Animation has moved on from the time when each movement had to be drawn and photographed separately, to the use of computers to create even-more realistic pictures and spectacular special effects.
