ABSTRACT
The composition of a shot is affected by the distance of the camera from the subject and the lens angle that is used. This will make a difference to the size relationships within the frame. The size relationship of objects in a field of view is known as the perspective of mass. Put simply, the closer an object is to us the larger it will appear and vice versa. The image of an object doubles in size whenever its distance is halved. This is a simple fact of geometric optics and it applies to a camera as it does to the eye. Adjusting the camera distance and the lens angle can provide the size relationships required for a composition.
