There are various degrees of close-up depending on how tight (zoomed in) the shot is. The terminology varies between countries and even different companies, but in general, these are:
* Medium Close Up ("MCU" on camera scripts): Halfway between a [[mid shot]] and a close-up. Usually covers the subject's head and shoulders.
* Close Up ("CU"): A certain feature, such as someone's head, takes up the whole frame.
* Extreme Close Up ("ECU" or "XCU"): The shot is so tight that only a detail of the subject, such as someone's eyes, can be seen.<ref>[http://www.askthecameraman.net/Camerawork/shot_sizes_the_extreme_close_up/ Ask The Cameraman: Shot Sizes: The Extreme Close-Up] {{webarchive |url=https://web.archive.org/web/20110610002654/http://www.askthecameraman.net/Camerawork/shot_sizes_the_extreme_close_up/ |date=June 10, 2011 }}</ref>
* Lean-In: when the juxtaposition of shots in a sequence, usually in a scene of dialogue, starts with medium or long shots, for example, and ends with close-ups.
* Lean-Out: the opposite of a ''lean-in'', moving from close-ups out to longer shots.
* Lean: when a ''lean-in'' is followed by a ''lean-out''.
When the close-up is used in the shooting, the subject should not be put in exactly the middle of the frame. Instead, it should be located in the frame according to the [[golden ratio|law of the golden section]].
