The cinematographer selects the camera, film stock, lenses, filters, etc., to realize the scene in accordance with the intentions of the director. Relations between the cinematographer and director vary; in some instances, the director will allow the cinematographer complete independence; in others, the director allows little to none, even going so far as to specify exact camera placement and lens selection. Such a level of involvement is not common once the director and cinematographer have become comfortable with each other; the director will typically convey to the cinematographer what is wanted from a scene visually and allow the cinematographer latitude in achieving that effect.
