Partly, and I usually turn it down because I don't like it. But also 4000dpi
is higher resolution than any digicam, so you should expect softer images
when viewing at one screen pixel per image pixel. On top of that, some slide
scanners have trouble getting good focus from center to edge, because of the
curvature of the slide.
