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 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 farthest objects that appear in acceptably sharp focus in a photograph. It is heavily used in photography, film and computer graphics as a creative style element, 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 large 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 these lengthy calculation times.

The term "Bokeh", which in Japanese literally means "blurring", has been introduced into the film, photography and computer graphics industries to describe the out-of-focus blur characteristics. It is determined mainly by the shape of the camera lens and can be seen best 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.

In its most advanced and powerful mode, Depth Of Field Generator PRO uses a specified depth map to derive an accurate DOF effect. A Depth Map is a greyscale image where the grey level at any given point represents the distance of the object from the camera at the same point in the original image.

Most 3D Computer Graphics applications are easily capable of producing depth maps along with the rendered image. For photographic images, the user has to create the depth map manually which can be greatly facilitated through the use of the filter's powerful gradient functions.

Depth of Field Generator PRO has been developed, tested and extensively used for production, ensuring its reliability and performance in today's creative media industry.
