Shot size describes how much of a subject and its surroundings appears within the frame. It does not initially tell you how long the shot lasts or the height from which the camera looks. A close-up may be brief or sustained, from above or at eye level. Separating these choices makes a scene easier to describe without reducing every image to one technical label.
From space to detail
In a wide view, the setting matters in relation to the figure. A whole person may look small inside a station, while a tighter image lets the same person dominate the frame. Medium sizes often include enough of the body to reveal gestures, whereas closer views make finer facial information available. Exact terminology varies between teaching systems and languages.
Use the categories as reference points and add a description when necessary. “Both people shown from the waist up” is more precise than an uncertain label. University introductions to framing likewise stress that categories become analytically useful through their relationship to the scene. Memorising a list does not explain an effect.
Three views of a conversation
Imagine two people at a kitchen table. A wider view reveals that one sits beside the door while the table separates the other from the exit. A tighter shot might show a hand nervously turning a spoon. A close-up may concentrate on a look while excluding the hand.
None of these views automatically contains the whole truth. When the image changes, ask what information arrives and what disappears. If a face fills the frame while someone stands up outside it, your attention is directed differently than it would be in a shared view. The selection creates a particular distribution of knowledge.
Notice a change rather than every label
On a second viewing, look for one development instead of naming every shot. Does the conversation gradually become more tightly framed? Does the film remain unexpectedly distant during an emotional event? Closeness may encourage involvement but can also feel oppressive. Distance may provide an overview or keep the audience apart from a character.
Record the moment and an observable consequence. “After the question, we can no longer see the hands” can be checked. “The camera reveals the soul” is an interpretation that needs support. Then connect observation and meaning: perhaps emphasis shifts from an action to a reaction. Allow for more than one reading when the evidence remains open.
