depth of field

n.
In photography and cinematography, the distance between the nearest and farthest elements of a shot that appear sufficiently sharp in the image. The elements that fall outside the depth of field for an image appear out of focus.

depth of field

n
(Photography) the range of distance in front of and behind an object focused by an optical instrument, such as a camera or microscope, within which other objects will also appear clear and sharply defined in the resulting image. Compare depth of focus

depth′ of field′


n.
the range of distances along the axis of an optical instrument, usu. a camera lens, through which an object produces a relatively distinct image. Also called depth′ of fo′cus.
