depth of ield

I try to create depth of field in my rendering but without succes. Fysical camera is off. Depth of fieldbox is marked. Even increasing the aperture to 0.5 has no effect.
Are there any other settings that i have to change.
I use the latest build.

Thanks,

Aperture is measured in Rhino units, so try to find something around 1..3cm.

Re: depth of ield

aperture was the problem. I turned it up to 2 and it worked fine.

Thanks!
