Reaction Shot
Kuleshov effectAssociative reaction construction
A reaction shot shows a character's response to an event, a line, or an unseen stimulus. The important action is watching; the face (or body) is the cut.
Narrative function
A reaction shot is coverage of receiving. The gunshot, the insult, the courtyard window: we often learn what it meant by looking at the person who saw it.
Meaning can be constructed between shots. A relatively still face reads differently depending on what came before, which is the Kuleshov lesson, not a demand that you fake a historical clip.
It is the wrong tool when the speaker's line still needs to be seen, or when you over-act the response so the audience is told the emotion. It is a function, not a size: often a close-up, sometimes an MCU, occasionally a full-body flinch.
How it works
Point the eyeline at the stimulus, even if that stimulus is offscreen. Hold.
Minimize explanatory mugging if you want the cut to do the work. Match Look Space and eyeline to the previous shot.
Size is usually Close-Up or Medium Close-Up. Prompt: Reaction close-up of [Subject] receiving news they cannot speak yet, the face as the cut.
When to use it
Use it when the important action is watching: the face after an offscreen shot, the listener who cannot speak yet. Do not use it as a blink after every clause, and do not perform the entire emotion so the juxtaposition has nothing to do.
Compared with similar shots
A Close-Up is a size; a reaction is why that size is here. Over-the-shoulder coverage still includes the partner as a shoulder; a reaction single can drop them.
A Cutaway may be a non-human comment; a reaction is a person's response. Keep the face fixed if you want to test Kuleshov; changing the expression changes the experiment.
In film
The Godfather often lets receiving carry the beat. Whiplash cuts to the face that has to survive the next bar.
Rear Window builds Jeff's looks so courtyard views change what the same face means. Grammar: watch the watcher.
- Rear Window 1954Jeff’s looks acquire different meanings through the courtyard views placed beside them.
Prompt it
Name receiving. Example: Reaction close-up of [Subject] receiving news they cannot speak yet, the face as the cut.
Specify eyeline offscreen or toward a known object. For video, hold a small physical change (a swallow, a blink) rather than a tour of expressions.
What usually goes wrong
The usual wrong cousin is a generic Close-Up of the speaker, or an overplayed grimace. The tell is mouth moving through the line, or eyebrows explaining the plot.
Fix: this person is receiving, not delivering. Point the eyes; hold.
Questions
What is Reaction Shot in film?
A reaction shot shows a character's response to an event, a line, or an unseen stimulus. It is a coverage function: the important action is watching, and the face or body is what the cut is about.
Reaction Shot vs Close-Up
A close-up is a crop: head and upper shoulders. A reaction shot is a job: this image exists because of what was just seen or heard. Reactions are often close-ups, but a close-up of someone speaking is not a reaction.
When should I use Reaction Shot?
Use it when watching is the event and the audience should read the receiver. Do not stack one after every sentence, and do not over-act the face if the cut is supposed to supply meaning.
How do I prompt Reaction Shot for AI image or video?
Write Reaction close-up of [Subject] receiving news they cannot speak yet, the face as the cut. Put the eyeline in the prompt. Keep the expression restrained unless the scene needs a big flinch.
