User Manual

Controls Tab
The Controls tab contains all the primary controls necessary for customizing the defocus
operation.
Filter
Use this menu to select the exact method applied to create the defocus. Gaussian applies a
simplistic effect, while Lens mode creates a more realistic defocus. Lens mode takes
significantly longer than Gaussian.
Lock X/Y
When Lock X/Y is selected, this performs the same amount of defocusing to both the X- and
Y-axis of the image. Deselect to obtain individual control.
Defocus Size
The Defocus Size control sets the size of the defocus effect. Higher values blur the image by
greater amounts and produce larger blooms.
Bloom Level
The Bloom Level control determines the intensity and size of the blooming applied to pixels that
are above the bloom threshold.
Bloom Threshold
Pixels with values above the set Bloom Threshold are defocused and have a glow applied
(blooming). Pixels below that value are only defocused.
The following four lens options are available only when the Filter is set to Lens.
Lens Type
The basic shape used to create the “bad bokeh” effect. This can be refined further with
the Angle, Sides, and Shape sliders.
Lens Angle
Defines the rotation of the shape. Best visible with NGon lens types. Because of the
round nature of a circle, this slider has no visible effect when the Lens Type is set
to Circle.
Lens Sides
Defines how many sides the NGon shapes have. Best visible with NGon lens types.
Because of the round nature of a circle, this slider has no visible effect when the Lens
Type is set to Circle.
Lens Shape
Defines how pointed the NGons are. Higher values create a more pointed, starry look.
Lower values create smoother NGons. Best visible with NGon lens types and Lens
Sides between 5 and 10. Because of the round nature of a circle, this slider has no
visible effect when the Lens Type is set to Circle.
Clipping Mode
This option determines how edges are handled when performing domain-of-definition
rendering. This is profoundly important for nodes like Blur, which may require samples from
portions of the image outside the current domain.
 Frame: The default option is Frame, which automatically sets the node’s domain of
definition to use the full frame of the image, effectively ignoring the current domain
of definition. If the upstream DoD is smaller than the frame, the remaining area in the
frame is treated as black/transparent.
