The improvement in sharpness going from the Epson Filmscan 2400dpi
scanner to the Nikon LS30 2700dpi scanner was astonishing.  I wonder
if the Nikon focusses more accurately on the *surface* of the film hence
it tends to show surface defects more?  Has anyone tried manually
adjusting the focus a little to see if it's possible to defocus the dust
and scratches without losing too much sharpness in the image?
