The Frame

The frame of view can be considered on three planes; the X-axis (horizontal plane), the Y-Axis (vertical plane), and the Z-axis (depth).

NTSC video format adheres to a 4:3 aspect ratio, which constrains the X-axis and the Y-axis.

The Z-axis is affected by shot composition (i.e. foreground, middle ground, and background) and by the depth-of-field.
