I've uploaded some more scan examples for any interested parties, scanned
with the Nikon LS-8000ED.

This is a scan of a Provia 100F transparency, in medium format, 6x6.  The
picture was taken with a 150mm lens (equivalent to 90mm on a 35mm camera),
roughly 1/250 at f/5.6 or so, as I recall.  The photo was shot handheld.
The location was the Disney Studios Park in Paris.

The scan was performed with the Nikon glass MF strip holder, 14-bit mode, 4x
sampling, dICE turned on, GEM and ROC off, superfine scan (1 CCD) off, auto
focus and exposure, no other adjustments from defaults.

The files are as follows:

... A reduced-size copy of the raw scan from the scanner.  This is a 16-bit
TIFF of about 2 MB; it is identical to the original, apart from being
downsampled to 1/223 of its original size (from 8964 pixels on a side to 600
pixels).  You can see that the entire frame is covered.  The blurred stuff
just to the left of the frame itself is just a reflection of the
transparency on the side of the film holder.

Since this is a TIFF, you won't be able to see it in your browser, but you
can download it and open it in Photoshop.

... An original-size excerpt from the original scan, showing detail
resolution.  No unsharp masking or anythign done.  This part of the photo
was also the original focus point in the photograph itself.

The scan after adjustment in Photoshop.  Adjustment consisted of changing
the curves to brighten up the scan a bit and to make the color balance match
the original transparency on a light table.  The original transparency has
better contrast, but this is the best that can be done for a CRT display.  I
also cloned out a tiny spot of Newton's rings in the sky in the original.

If you want to see how well the scanner holds the shadows, load the TIFF and
crank up the curves in Photoshop; you can see that there is more detail in
the shadows than are normally visible on a CRT.

Overall it seems to do a pretty good job.
