This is not true. If you specify a profile for your monitor (e.g., sRGB,
or a custom profile generated with a measuring device) VueScan will
adapt its output to the screen, whatever the color profile of the output
file is.
On the other hand, before you post images to the web, you should always
convert to sRGB.

With NikonScan 4.0.2, I get similar dissapointing results as yours when
I have "Image Enhancer ON" and "Digial Ice on Fine".
For best results, I turn OFF Image enhancer and Digital Ice on "Normal". |

And you claim that this profile would convert Adobe color space
to a profiled sRGB??? I will not exclude that such profile can
be generated, I think however that in this case you are mistaken.

Nice description. I have only one question: The images created by
vuescan directly and the one created via NikonScan->vuescan look rather
different, too. You state that the image directly from vuescan looks
like the one you see projecting the slide. But the one NS+VueScan really
looks -- well -- not poor, but quite different. Is there a reason for this?
Best wishes

I am not sure what causes the difference, except that by elimination
of possible reasons I can only suspect that ICE+GEM processing, which
I use for my raw files, in not neutral to the color balance!
Anyway, please take this method and its description with the
caution becasue it relate to older NikonScan and older Vuescan.
We do have a new NikonScan 4 now, which has changed quite drastically
in its color reproduction (without Nikon's description what and why.)
The nasty magenta cast in green reproduction is gone. Also the "raw
files" look completely different! NikonScan 3 raw files were very
dark, white was at approx. 60% level(!!), whereas NikonScan 4 raw
files have gamma elevated significantly and this provides much better
latitude for a processing in Vuescan or in Photoshop.
Furthermore, Vuescan made also significant advances. It supports
now color profiles and its color reproduction has improved because
Ed used the profiles to calibrate the build-in profiles as well.
Also many of the posterization problems in conjunction with black
point setting have been resolved.
I still use this workflow, albeit I am by myself not conclusive
regarding Media type: "To Image or not to Image" its the question!
Image seems to be working perfect with the scanner profile, but
"Media type=Slide" allows to setup the film base color.... In some
situations however (low contrast images or low temperature such as
late evening) "Media type=Slide" does not provide satisfactory
results or even fails completely, whereas type=Image seems to
be very linear in the processing of the raw data.
Now its the time for Christmas... We have to hit the road to
be ahead of the traffic!
Merry Christmas to everybody!

Yes, I experienced this problem again and again. I am scanning several
hundred (some thousands) of slides (most of them Provia, some Sensia)
first to raw files, then to jpg/png/whatever and there are always these
problematics cases.
It is strange because you hear again and again "Use Image" but I have
made the experience that the Slide also works quite often very good.

I tried this workflow, and I find Vuescan just produces horrible
overexposed/flat scans from the 'raw' NikonScan files. I'm also unable to
select "slide" or "image" in the scan from file dialogue, it will only let
me select "colour photo" or something to that effect. The other choices are
"b/w photo," "newspaper," etc. Occasionally it shows the various film
choices when I fiddle with it, but this is obviously just a bug, because
selecting "slide film" produces a black and white scan (the selection is in
the same place as "b/w photo" on the list). I would love to be able to just
do 'raw' scans in NikonScan and clean them up later, but so far the results
have been dreadful.
As far as the original example on my pbase account (the first one),
NikonScan's colour is much closer to the original than either Vuescan or
Silverfast, the slide *does* have a very dramatic purple cast. The
NikonScan raw/Vuescan from file result looks quite nice after I clean it up
with curves, but it's nothing whatsoever like the original slide.

I am afraid, you do something wrong and I can only repeat a suggestion
to post a raw file of a moderate size, 14bit 800x600 pix or similar
and lets give it a try.
