Hello,

How MSU handles the histograms ?
It's often the histograms is like truncated at the ends 'maybe most
using negs), like if the tonal range of the scanner was too small for
the neg of positives i scan (even in 16 bits). Howerver, i think the
tonal range capability of the scanner should normally cover most of the
pictures.

Is the tonal range modified by MSU ?
How to check the density of a dia using MSU, is it only possible ?

Why are the ends of the histograms often so vertical ?
Same question about the max values og the histograms, there is often
some "plate" on the histograms curves. does the soft set artifically
plates for some color range values ?

Regards

Yes, the Dimage Scan Utility is known for clipping histograms,
especially when scanning negatives but also when scanning slides. This
is not a hardware problem (at least it isn't for the two Minolta
scanners I own/owned).
For many Konica Minolta scanner owners this is one of the main reasons
to use third-party software, such as VueScan or SilverFast.

Don't worry about that - it's just the limited height of the frame that
is used for displaying histograms.

Which models are you referring to? Under what settings are the
histograms clipped? Based on what source(s) can you claim that "the
Dimage Scan Utility is known for clipping histograms"?

From my own experience: Minolta Dimage Scan Speed and Minolta Dimage
Scan Elite 5400 (original version)
Under what settings are the
histograms clipped?

In my experience under any setting, even if the software is not allowed
to perform any after-scan adjustments. I haven't found a workaround
(except for using third-party software), although it might be possible
to fool the software by deliberately including clearly overexposed
and/or underexposed areas in the original.
The clipping effect with negatives is more severe than it is with slides.

On my own experience and several other reports on the web and in this
newsgroup,
For instance, search for the string "clip" in these threads using your
