Photos often include objects in the frame that were just there at the time of the picture taking. Roland Barthes writes that these objects, of little or no meaning to the photographer, can greatly effect the viewer; each viewer constructs his or her own meaning when beholding the photograph, and the intentions of the photographer become rather unimportant.
The mark of a “paparazzi” photo is an abundance of these objects, in this case, empty bottles and glasses, and the formal dress of the subjects. Pose also is important. The subjects know they are being photographed but try not to look like it.
