Final answer:
Perspective is a filmmaking technique that changes how viewers perceive objects and scenes, using spatial relationships and camera angles to alter perception and emotion.
Step-by-step explanation:
The filmmaking technique that changes the way the viewer perceives objects and scenes is called perspective. Perspective involves manipulating the spatial relationships within a scene to achieve a certain effect. Techniques such as scaling objects to show distance or depth, placing objects strategically within the frame to lead the viewer's eye, or employing different camera angles can all alter the viewer's interpretation of a scene. For example, atmospheric perspective changes the color and clarity of objects to simulate distance, making faraway objects appear lighter and less defined. Additionally, the point of view from which a scene is shot can dramatically affect the emotional impact on the viewer and what they perceive as important or focused on within the film.
