The spectator is now inside the film, no longer conceived as a circumscribed form within a predefined space but as the very field within which the experience takes shape.
...the point is not to produce the mechanical phenomenon of the shutter’s action but to dramatize it; it is not about the phenomenological reduction of the cinematic projection, but its reconstruction.
