The BCC Pyramid Blur filter emulates the look of shooting in soft focus or with lens diffusion. This filter allows you to blur the horizontal and vertical components of the image separately.
BCC Pyramid Blur uses a refined algorithm that speeds rendering approximately 20 – 40 percent. When you create new blur effects, you should use this filter. To maintain compatibility with existing BCC settings, use the BCC Blur filter.
The built in PixelChooser, with integrated mocha planar tracking allows for greater control over which areas of the image the filter should affect.
