and have i missed it or does the Depth of Field only control the setting the back, or rear of the range in focus?

Everything between the lens and this focus control point remains IN focus -right? So seems there is no way (using Poser alone) to create a field of focus with blurred areas both IN FRONT and behind the focal point? (so, no selective range of focus even in P6?)

and re GRAIN, haven't tried yet, but manual page 120:

"NOTE
IF THE RESULTS OF YOUR DEPTH OF FIELD SETTINGS ARE TOO GRAINY IN THE BLURRED AREAS, TRY RAISING THE NUMBER OF PIXEL SAMPLES. DOING SO WILL RESULT IN A SMOOTHER EFFECT, BUT INCREASED RENDER TIMES."
