Distance parameter. And truthfully, it is the Blur Focal Distance
property that really makes this effect so powerful. I deselected the

These results are nothing short of spectacular, especially con-
sidering how easy it was to set this project up. But the real power
here is in the ability of the Lens Blur effect to animate the Blur
Focal Distance property. This can create shifts in the focal plane
