Depth Of Field Generator PRO v3.0.70 for Adobe Photoshop
януари 7, 2007
Depth of Field Generator PRO is the result of ongoing research, development and programming collaboration between Richard Rosenman and Martin Vicanek in an effort to produce a Photoshop compliant plugin capable of delivering high quality, sophisticated Depth of Field and Bokeh effects quickly and efficiently as a post process.
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 wavelength of light.
Depth of field is heavily used in photography, film and computer graphics as a creative element, 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. Digital cameras, in particular, usually show a wide depth of field – i.e. they are more tolerant to defocus effects. While this may be welcome in some instances (e.g. snapshot applications), it is often a serious deficiency in others (e.g. portraiture/macro photography). In computer graphics, physically accurate DOF can be effectively generated using complex ray tracing techniques which tend to increase rendering times significantly. As a result, most computer generated broadcast and film production often lacks DOF as a result of the lengthy calculation times.
