Photography and optics

The near-to-far zone that looks acceptably sharp

In imaging optics depth of field is the range of distances in front of and behind the focused plane within which a subject still looks acceptably sharp, set by the aperture, the focal length, the focus distance, and an agreed circle-of-confusion tolerance for what counts as sharp. General photographic practice shows that a smaller aperture deepens the zone while a wide aperture narrows it, giving the shallow focus that isolates a subject against a blurred background. The referent is a sharpness zone of an optical system, distinct from the related but different depth of focus measured at the sensor side of the lens. It is a standalone imaging construct rather than a cross-field collision.[1]
