Lens Shape

The BCC Lens Shape filter emulates a lens blur defocus/rack-focus effect where out of focus highlights of an image clip take on the shape of the lens diaphragm, however, the Lens Shape filter takes an image input and uses this for the highlight shape.

When a lens is used at it’s maximum aperture (fully open / set to the smallest f stop number) the out of focus highlights are typically in the shape of a circle, however, when the lens is stopped down (set to something other than the smallest f stop number) the blades inside the lens shape the out of focus highlights into multi-sided shapes. This filter includes a pop-up that can be used to match the different looks that can be achieve in the physical world based on the lens aperture setting. This pleasing optical result is referred to in photographic terms as Bokeh.

The BCC Lens Shape filter also includes a comprehensive depth of field (Z-Depth) option, whereby a separate image can be used to control the depth and position of the focus field.

The built in PixelChooser, with integrated mocha planar tracking allows for greater control over which areas of the image the filter should affect.
