Controls Tab
The Controls tab contains all the primary controls necessary for customizing the Vari Blur
operation.
Method
Use this menu to select the method of Blur used in the filter. The selections are
described below.
 Soften: This method varies from a simple Box shape to a Bartlett triangle to a decent-
looking Smooth blur as Quality is increased. It is a little better at preserving detail in
less-blurred areas than Multi-box.
 Multi-box: Similar to Soften, this gives a better Gaussian approximation at higher
Quality settings..
 Defocus: Produces a flat, circular shape to blurred pixels that can approximate the look
of a defocus.
Quality
Increasing Quality gives smoother blurs, at the expense of speed. Quality set to 1 uses a very
fast but simple Box blur for all Method settings. A Quality of 2 is usually sufficient for low Blur
Size values. A Quality of 4 is generally good enough for most jobs unless Blur Size is
particularly high.
Blur Channel
This selects which channel of the Blur Image controls the amount of blurring applied to
each pixel.
Lock X/Y
When selected, only a Blur Size control is shown, and changes to the amount of blur are applied
to both axes equally. If the checkbox is cleared, individual controls appear for both X and Y
Blur Size.
Blur Size
Increasing this control increases the overall amount of blur applied to each pixel. Those pixels
where the Blur image is black or nonexistent are blurred, despite the Blur Size.
Blur Limit
This slider limits the useable range from the Blur image. Some Z-depth images can have values
that go to infinity, which skew blur size. The Blur Limit is a way to keep values within range.
