filmscanners: film sharpness
(snip) I too have noticed funny things with the focusing with my SS4000
(running Vuescan, don't know about PCI - haven't used it in a while).
I've scanned a slide, found too much dust, re-scanned it and found that
the focusing had changed slightly - the dust was in sharp focus, but the
image was slightly less sharp. Don't know if this is a software issure
or something to do with the slide holder. I've noticed that when you
insert a slide into the holder, it is usually not flat - that is the
holder doesn't do a good job of keeping the slide all in one plane (snip)
what you all could be describing is the classic situation of a negative
'popping' due to the heat of the lights. well known to all darkroom enlarger
users
More interestingly...
is this one reson why Nikon are using LED lightsources (much cooler)
