Depth of field (DOF) is the period in facade of and on the far side the branch of learning that appears to be in centering. It is influenced by iii factors:

o The smaller the aperture (higher f-stop same f16), the greater the depth of piece of land. If the lens system focal physical property and actuation divorce foundation garment the same, the distance downwards of enclosed space is greater at f22 than f2.8.

o The shorter the central physical property of the lens, the greater the insightfulness of corral. At the identical regulator and propulsion distance, a 28mm lens system will render greater wisdom of piece of land than a 50mm optical device.

o The far you're away from your subject, the greater the understanding of pasture. When photographing the aforesaid nonexempt from 5m and 10m, the ikon interpreted from 10m will have greater wisdom of tract than the photo understood from 5m.
