(or vice versa) during a shot, giving a cinematographic degree of freedom. But unlike changes in camera position, zooming does not change the perspective (the relative sizes of near and far objects); it only magnifies or reduces the size of the entire image as a whole. Zooming can either be performed towards longer focal lengths, giving a "zoom in" effect: The filmed object will then increase in apparent size, and fewer objects become visible on film. Or it is performed towards shorter focal lengths, giving a "zoom out" effect: The filmed object will shrink in apparent size, and more objects come into view. The speed of the zoom allows for a further degree of cinematographic freedom. Combined with a dolly camera move it is possible to create the dolly zoom effect. Noticeable cinematographic examples for the use of slow zooms include the 1975 film '' Barry Lyndon'' by
