filmscanners: RE: Automatic "best focus average" solution for selecting focus point? (was RE: filmscanners: VueScan 7.2.11 Available)

Would more than five be necessary?  Five points in a domino pattern would
seem to cover the frame pretty well.  Even five points would take a long
time to do.  Nine would be painful. =8^o

I don't have the means to measure it, but I'd guess that nine focus measurements
would take about as long as using the film strip holder (doesn't help those
with mounted slides, I know).
