This noise is post processed, no? What's the difference between that and
jitter?

me neither. i think too much noise makes it look like heavy jpeg
compression.

I guess that setting some jitter may slow down (more!) the render. A
postprocessed noise lets you add noise by trial-and-error without having to
re-render the scene too many times.

Very, very nice Fernando.
<rant>
You know, it's really funny- I frequent forums for the Max, Brazil, and
Universe3D packages and many times I will notice people talking down on POV
users. I then see images such as this and just want to flood the forums with
links to these images just to show what truly creative and talented people
can do with this package -without the benefit of a modeller (or at most
Moray, that, while good, is not anywhere in the same league as Max etc.)- in
the vain hope of deflating their egos.

Ok, sorry about that. Again, really nice pic man!

It depends on what is being jittered and for what reason. :)
Sometimes jitter is used along with multiple samples per pixel to
minimize what might otherwise be large errors in the value of a
particular pixel. In a case like this, it is actually reducing the
apparent noise {in that case, jaggies) of an image.

This version is definitely better, the green velvet table would have been
nice, but the wallnut finish is just as good.

These are better.
I see the noise, and now that I do, I'm wondering how much it actually helped in
this particular case since you used lower focal blur settings. Which then leads
me to wonder if film grain noise couldn't be simulated with screen.inc and the
blurred patterns trick.
