Angle of view and depth of field
Angle of view is directly related to the focal depth of
field (the distance in front of and behind the subject
that the camera is able to bring into focus). The
greater the angle of view (wide angle), the greater
the depth of field. When the angle of view is
narrow (telephoto), the depth of field decreases.
