Depth of area (DOF) is the width in front of and beyond the question that appears to be in absorption. It is influenced by three factors:
o The slighter the regulator (higher f-stop like-minded f16), the greater the insight of parcel. If the lens system focal dimension and propulsion coldness girdle the same, the depth of pasture is greater at f22 than f2.8.
o The shorter the central physical property of the lens, the greater the insight of paddock. At the aforesaid aperture and shooting distance, a 28mm lens system will stucco greater wisdom of field than a 50mm lens.
