What is Rack Focus?
Rack focus is a technique commonly used in filmmaking and video editing to shift the focus between two or more subjects within a single shot. It involves adjusting the camera’s focus from one subject to another, creating a smooth transition that draws the viewer’s attention to different elements of the scene. This technique is frequently employed to enhance storytelling, convey emotions, or highlight significant details.
How Does Rack Focus Work?
Rack focus works by manipulating the camera lens to change the focal distance and shift the focus point within the frame. By adjusting the lens’s focus ring or utilizing autofocus capabilities, the video editor or filmmaker can control which subject appears sharp and in focus while blurring the other elements of the scene. This controlled transition of focus can be executed gradually or quickly, depending on the desired effect.
