What does a reaction shot typically involve?

A reaction shot is a specific type of film technique that focuses on a character's emotional response to an event or dialogue occurring in the scene. The purpose of a reaction shot is to provide insight into how a character feels about what is happening, enabling viewers to connect more deeply with the story. By showing a character's facial expression—such as surprise, happiness, fear, or sadness—this technique allows the audience to understand the emotional stakes of the moment.

The other choice options represent different cinematographic techniques but do not encapsulate what a reaction shot is. Revealing a character's environment, showing a subject in motion, or presenting a wide shot of the general scene do not specifically focus on capturing a character's emotional response, which is the hallmark of a reaction shot. Thus, C accurately describes the essence of a reaction shot in video production.
