Beautiful result, Joel.

Short version: Here are a pair of images which show some advantage in
maintaining a blurred background while presenting a sharp main image.
Control: single photo shot at f16:

FS'd version from 4 photos at f5.6:

For anyone interested -- I stopped testing focus stacking with a controlled
background (I was using a black cloth background) as there is no point. I
also ran into some weird, unpredictable behavior in the way PS "sees" the
solid background, or it may stem from a different problem, described in the
next paragraph.
I was able to stump PS pretty badly by focusing too close to the nearest
part of the flower I wanted in focus and attempting to use fewer photos (3)
and blend a greater range of in-focus areas across the entire flower. I
used f8 for this and I think the problem arose because the difference in
mag ratio among the three shots ended up being too great, actually changing
the size of the main part of the flower. My take-away is that it is better
to use more images, which works better with a larger aperture anyway, in my
case f5.6. I haven't tried anything wider than that yet but plan to and
will post if I have any success.
