You will see in the binaries that I told the truth. :)

I don't know exactly whether it is accurate or not, but it is for Povray and
it does not depend on me.
Anyway, i noticed that reflected objects do not seem to follow physical laws
in terms of blurring, indeed. Perhaps i am wrong. I know that curved surface
can behave as lens and thus change the focal point or the focal distance.

As i can remember, my focal blur settings for boules_final.jpg were :
Variance 0
Confidence 0.999...
Count (?) 200
These settings were required to avoid noise and artefacts (which has already
be reported on this newsgroup).

Best regards,

Jerome
