Check color spaces, monitor calibration (is it honored in Nikon Scan?),
and how big the preview image is in NikonScan. This stuff is tricky at
first, but does sort itself out when you are persistent. What works
best for me is to keep scanner software as "stupid" as possible and
do virtually all correction in an image editor. The only exceptions
I normally consider are:
1) Adjusting "exposure", an analogue setting for some scanners, that
apparently either brightens/dims the scanner bulb or lengthens/shortens
the amount of time the scanner CCD spends on a given scan line. Use
it to shift the histogram so it's not bunched up on the right or left
too much.
2) Focusing with the scanner.

Why is it when I open a scanned image saved as TIFF files in Photoshop
the quality is much deteriorated compared to the original scan. That is,
if I open the file in Nikon Scan 4.0 the image is great. In Photoshop
sharpness is reduced and there are noise artefacts as well.
Any idea?
