The long shot similarly helps us to establish location and atmosphere, and to follow the pattern or purpose of movement. An early productional habit of beginning most scenes with an establishing long shot has died hard, for it has the merit of letting the viewer know where he is supposed to be, from the start. Sometimes it is preferable, however, to build up his impressions gradually, shot by shot. By satisfying his curiosity a little at a time, we can encourage a continually growing interest, and a sense of expectation.
