"Private films are "affirmative statements," spontaneous film recording of the amateur reflecting on his own world: the way he saw a particular thing at a particular time and in a particular way. What we later evaluate as a film-statement is only a reflection in the moment of filming. And as an intervention it has an influence on the event. The presence of the camera can be sensed, which affects the home movie behavior. Pushing the button of the camera is an immediate reflection on the present situation. The world "happens" and we record a bit of it."

- Wittgenstein, Tractatus Logico Philosophicus.
