Like large format view cameras, the Swing/Shift system employs bellows, swings, tilts, rises, falls & shifts for a variety of effects. You can distort the shape of a subject, remove unwanted objects from the frame, or shoot straight into a mirror without catching the camera's reflection. Swing and Tilts also provides nearly total control over the focus plane, for extremely deep, or shallow, depth of field. Distant objects and extremely close ones can both be sharp in the same frame. Or you can limit focus to a particular object, isolating it even from objects the same distance from the lens. Tilting or swinging the lens can alter both apparent depth of field and an object's shape. Shifting the lens lets you reposition objects within the frame without changing the angle between the object and the film plane. The combination of these movements gives you control over perspective distortion which affects the proportions of objects.
