What is the intention behind the use of an insert shot?

The intention behind the use of an insert shot is to show a small detail of the action. Insert shots are typically employed to focus the audience's attention on a specific object, character expression, or piece of action that is significant to the narrative. For instance, a close-up of a character's hand reaching for a key prop can create a moment of significance in the story, underscoring its importance or revealing a character's state of mind.

This technique enhances storytelling by allowing viewers to connect more deeply with the material, providing context that might not be captured in wider shots. By focusing on details, insert shots can convey emotions or plot points succinctly, making them a powerful tool in visual storytelling.
