Regarding talk of DOF filters, has anyone taken a look at other 
defocusing techniques than just doing a normal gaussian blur? I ran 
across this site a while ago, with a paper and GPL source code that a 
guy made at Digital Domain:
http://www.cinenet.net/~spitzak/conversion/index.html

The example here is particularly convincing:
http://www.cinenet.net/~spitzak/conversion/blur.html   (bur with 
rolloff)

This would be great for a filtered approach - in my experience in using 
post filters on the Z depth for DOF, they often have the typical, 
cheap-CG 'gaussian blur' feel, which looks horribly fake with muddy, 
blurred out highlights (no bokeh effect - 
http://homepages.ihug.com.au/~parsog/Guy/bokeh.html ).

Please forgive me if the Zblur/etc plugins do already use a similar 
method - to my eye, they don't seem to.

Cheers,

Matt
