You're right. Of course, it's good for "focusing attention" on a particular
part of an image; but there are other, opposite uses for focal blur where
you want to "de-emphasize" an area (the foreground.) without affecting
anything else.  That's my primary reason for wanting an alternate type of
blur.

Good point, and that's the way real lenses work (making hyperfocal distance
possible.) I wasn't aware that POV worked that way; I'll have to experiment
and see.
