Parameter Description
Quality menu Controls the quality of the Depth of Field blur. This
is basically an anti-aliasing level control.
•Low
•Medium
•High
There is a significant rendering cost to using High.
Focal Length Sets the distance between the camera and the focal
point. If the object is at the focal point, it appears in
focus. As it moves away from the focal point, it loses
focus.
Depth of Field Sets the cameras depth of field.
If you adjust this parameter, the focal range from the
focal point is increased or decreased.
Sample # menu Sets the number of samples that are taken.
Higher values take longer to preview and render but
provide smoother blurring.
