What is the key purpose of leadroom in composition?

The key purpose of leadroom in composition is to provide space for movement. Leadroom refers to the area in front of a moving subject, particularly in the context of filming or photography. When a subject is in motion, having extra space in the direction they are moving allows for a more balanced composition and creates a sense of anticipation for the viewer. This technique is particularly important in dynamic shots like tracking or panning because it helps to convey the motion effectively and reduces the feeling of the subject being cramped or confined within the frame.

This concept plays an essential role in storytelling through visuals, as it can guide the viewer's eye and enhance the overall narrative by allowing the subject's movement to be more fluid and natural within the frame.
