Focal Depth When Use Target Distance is off, sets the depth from which the
camera is offset. Can range from 0.0 to 100.0, where 0.0 is at the camera's
location and 100.0 is in the extreme distance (effectively, infinity).
Default=100.0.
Low values of the Focal Depth give wildly blurry results. High Focal Depth
values blur the distant portions of the scene. In general, using Focal Depth
instead of the camera's Target Distance tends to blur the entire scene.
Sampling group
Display Passes When on, the rendered frame window displays the multiple
rendering passes. When off, the frame window displays only the final result.
This control has no effect on previewing depth of field in camera viewports.
Default=on.
Use Original Location When on, the first rendering pass is in the camera's
original location. When off, the first rendering pass is offset like all subsequent
passes. Default=on.
Total Passes The number of passes used to generate the effect. Increasing this
value can increase the effect's accuracy, but at a cost of rendering time.
Default=12.
Sample Radius The radius by which the scene is shifted to generate blurriness.
Increasing this value increases the overall blurriness of the effect. Decreasing
it reduces the blurriness. Default=1.0.
Sample Bias Weights the blurring toward or away from the Sample Radius.
Increasing this value increases the magnitude of depth-of-field blurring, giving
a more even effect. Decreasing it decreases the magnitude, giving a more
random effect. Can range from 0.0 to 1.0. Default=0.5.
Pass Blending group
The multiple depth-of-field passes are blended by dithering, which you can
control by the parameters in this group.
These controls apply only to renderings of the depth-of-field effect, not to
previews in viewports.
Normalize Weights Passes are blended with random weighting to avoid
artifacts such as streaking. When Normalize Weights is on, the weights are
normalized, giving a smoother result. When off, the effect is a bit sharper but
usually grainier. Default=on.
