In photography, bokeh (derived from the Japanese (ボケ味) refers to the visually distinctive character of the out-of-focus areas of a photograph. Alien Skin’s Bokeh plug-in is a realistic lens simulator that allows you to alter the depth-of-field of a photograph after it has been taken. It can also be used to simulate tilt-shift and vignetting effects commonly used by photographers to draw the viewer’s attention to certain areas of a photograph.
