Camera distance (engl.
): The camera distance is a measure of how much of a filmed object is actually visible in the frame. Setting sizes describe how large the object appears in relation to its
surroundings and how detailed the shot of it is. Although the actual distance between the camera lens and the object can regulate the
setting size, it is actually a measure of the "apparent" distance between the two points. For example, in a
close-up the camera often seems to be very close to the object, but in reality it may be at some distance. Thus, different
lens types types (and thus different
focal lengths) have a great influence on the perceived distance of the camera to an object. The division into different setting sizes is closely related to psychological theories of proximity and distance between people, which are generally summarised under the term
proxemics.
One of the most common systems for classifying shot sizes is based on the human body and roughly distinguishes between
close-up) (CU), a
medium (or mid) shot (MS) and a
long shot (LS). Close-ups are all shots in which only one part of the body is shown. Semi-close-ups are shots that show about half of the body, while long shots show the whole body. Close-ups are further subdivided into extreme close up
extreme close up (ECU) and
medium close up (MCU). A similar procedure is used for long shots, resulting in a division into
extreme long shot (ELS) and
medium long shot (MLS). To simplify matters, a
standard set of abbreviations has been established in the system of setting sizes in the English language.
