![]() DOF 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 object distance from the camera. ![]() The term"bokeh".which in Japanese literally means "blurring", has been introduced into the film, photography and computer graphics industries to describe these particular out-of-focus blur characteristics. It is determined mainly by the shape of the camera lens and can be best seen on out-of-focus highlights which assume the shape of the lens aperture. A lens with few aperture diaphragm blades (say 5) tends to produce pentagonal highlights, whereas a lens with more aperture blades (say 7-8) tends to produce rounder (heptagonal/octagonal) highlights. Ultimately, a higher number of aperture blades will produce more circular highlights. ![]() DOF PRO now offers the capability to independently control the spherical aberration edge thickness. an important characteristic of optically-correct bokeh effects. This results in crisp bokeh edges matching real-world bokeh abnormalities. ![]()
