Is there a proper way to setup the depth of field filter for accurate results? When I focus on a foreground object my foreground and background objects are blurred but when I focus on my background object my background object gets sharpened and my foreground object gets sharpened. Is there a property or hack that sets a radius for what should be sharpened and blur everything outside of that radius? The focusDistance property appears to do nothing.

I was wondering the same thing. Can anyone help out with this?
