Thanks to digital cameras and smartphones, shooting pictures and video is virtually free. There is no cost for film and no need to develop it. Digital storage keeps getting cheaper and cheaper, and we are swiftly migrating to the cloud (probably, in an effort to secure our digital belongings and have access to them anywhere we are). These visual captures of anything that calls our attention have become one of our greatest sources of digitally generated content. And it is because of their ever-increasing size that we keep running out of space, over and over again.
