DOF PRO is the compliant plug-in to process digital images. Depth of field (DOF) is the amount of distance between the nearest and furthest objects that appear in acceptably sharp focus as seen by a camera lens. This field varies with the focal length of the lens, its f-stop setting, and the object distance from the camera. Depth of field is heavily used in photography, film and computer graphics as a creative element, and in typical examples ranging from portraiture to macro photography. In photography, DOF is governed by three factors: aperture, lens focal length, and shooting distance. Many consumer class cameras, however, do not provide sufficient and independent control of these parameters. In computer graphics, physically accurate DOF can be effectively generated using complex raytracing techniques that tend to increase rendering times significantly. As a result, computer generated broadcast, print, and film production often lacks DOF as a consequence of the lengthy calculation times.
