IPA: /ˈkloʊsʌp/
KK: /ˈkloʊsˌʌp/
A type of shot in photography or film where the camera is very close to the subject, often showing details like a person's face.
The director asked for a closeup of the actor's expression during the emotional scene.
Closeup → It is formed from "close" (from Old English "clōsan", meaning to shut or bring together) and "up" (meaning to a higher position or level). The word "closeup" refers to a shot or view taken at a very short distance, bringing the subject closer to the viewer.
Think of bringing something 'together' ('close') and moving it 'up' to see it better — that's why a closeup shows details up close.
