Use the Depth-O-Gram settings to refine focus values.
Depth blur effects control the amount of blur based on a depth of field matte. Depth blur settings are displayed in the Depth-O-Gram
tab.
A depth of field map (Z-depth map) can be connected to the node. Black portions of the map are in focus. White portions display
the highest level of blur. Note that a Z-depth map imported from another application may use the opposite convention and may
need to be inverted.
- Focus Plane
-
Set the distance of your focus point, that is, the point at which there is no blur on the image.
- Focus Offset
-
Set the distance between the focus plane and the near offset represented as a percentage of the total offset range. Select
50% to make the near and far offsets equidistant from the focus point.
- Focus Range
-
Set the distance between the near and far offset.
