What is observatinal ocumentarys?

Emphasizing the documentary filmmaker's arrangement in observing the subject's daily life and circumstances and documenting them with an unremarkable camera.

For example:                                                                                                               By conserving the observational mode, the director allowed the subject to forget the presence of the camera and behave more naturally, thereby letting the audience get a better sense of how she really feels about having such an unusual abundance of facial hair.
