Depth of Field
The distance in front of a camera in which all elements are in sharp focus. Bright light and a narrow lens aperture tend to produce a larger depth of field, as does using a wide-angle lens rather than a lens with a long focal length (telephoto lens). Depth of field is directly connected, but not to be confused with, “focus”, which refers to the quality (i.e. the “sharpness”) of an object in the image, whereas depth of field refers to the extent to which the space that is presented is in focus. For related information, see the entries on shallow focus and deep focus.
