With a dramatic increase of pictorial media around us that can be used to present and transmit things seen, such as digital cameras, mobile camera-phones, webcams, and image software, ever more people have become producers of pictures for others to see, and it is often not that clear how these pictures are used and for what purposes. Take, for example, cameras, which have become everyday artifacts that are part of ever more social situations. Cameras are used in several types of situations. In short, cameras have become ubiquitous companions of our everyday life.
This research focuses on two main research questions:
1) how do we use cameras at a time in which they are ever more available, and
2) how do these cameras mediate our actions?

In order to answer the research questions, this research is situated within a wider
context of a growing body of research on images and the visual, with a theoretical
perspective on pictures that is applied and extended to networked cameras and their uses. A larger context of visual orders based on related research is worked out in which non-professionals use camera pictures. Empirical case studies of actual uses are performed, and the ways in which the findings show cameras to mediate our actions are taken into account separately.
