In most films, logical coherence is achieved by cutting to continuity, which emphasizes smooth transition of time and space. However, some films incorporate cutting to continuity into a more complex classical cutting technique, one which also tries to show psychological continuity of shots. The montage technique relies on symbolic association of ideas between shots rather than association of simple physical action for its continuity.
Continuity editing can be divided into two categories: temporal continuity and spatial continuity. Within each category, specific techniques will work against a sense of continuity. In other words, techniques can cause a passage to be continuous, giving the viewer a concrete physical narration to follow, or discontinuous, causing viewer disorientation, pondering, or even subliminal interpretation or reaction, as in the montage style.
