Filter
This menu selects the filter used for the blur.
Box: This applies a basic depth-based box blur effect to the image.
Soften: This applies a depth-based general softening filter effect.
Super Soften: This applies a depth-based high-quality softening filter effect.
Blur Channel
Select one of these options to determine the channel used to control the level of blur applied to
each pixel. The channel from the main image input is used, unless an image is connected to the
node’s green Blur Image input.
Lock X/Y
When toggled on, this control locks the X and Y Blur sliders together for symmetrical blurring.
Blur Size
This slider is used to set the strength of the horizontal and vertical blurring.
Focal Point
This control is visible only when the Blur channel menu is set to use the Z channel.
Use this control to select the distance of the simulated point of focus. Lowering the value
causes the Focal Point to be closer to the camera; raising the value causes the Focal Point to
be farther away.
Depth of Field
This control is used to determine the depth of the area in focus. The focal point is positioned in
the middle of the region, and all pixels with a Z-value within the region stay in focus. For
example, if the focal point were selected from the image and set to a value of 300, and the
depth of field is set to 200, any pixel with a Z-value between 200 and 400 would
remain in focus.
Z Scale
Scales the Z-buffer value by the selected amount. Raising the value causes the distances in the
Z-channel to expand. Lowering the value causes them to contract. This is useful for
exaggerating the depth effect. It can also be used to soften the boundaries of the blur. Some
images with small depth values may require the Z-scale to be set quite low, below 1.0.
Common Controls
Settings Tab
The Settings tab in the Inspector is also duplicated in other Deep Pixel nodes. These common
controls are described in detail at the end of this chapter in “The Common Controls” section.
