[filmscanners] RE: Scanner calibration



May be, but at first the scanner once showed the ability to render clear
neutral colors, so bearing that in mind I still hope to figure out what went
wrong and to fix it.

I did a few test scans again and this issue seemed to drive me crazy.
The pink (not violet as I presumed previously) cast has back with no
relation to particular slide batch. Comparing scans done to Adobe RGB and
Scanner RGB (all performed in NikonScan as stand-alone application) opened
in NikonScan and Photoshop (set to Adobe RGB working space) independently
showed opposite results.
Image scanned into Adobe RGB seemed much more neutral then scanned to
Scanner RGB (which featured quite strong pink cast) while both opened in
Photoshop.
On the other hand, opening both versions of the image in NikonScan revealed
the Scanner RGB version to be more neutral then one scanned to Adobe RGB.

Now, the second image behaved in opposite way:
his Adobe RGB scanned version was covered by pink tint, while Scanner RGB
version is looking better (more balanced), while both opened in Photoshop.
Opening these in Nikons can produced opposite results: Scanned RGB version
is more balanced while
Adobe RGB scanned version featured quite heavy pink cast.

Now it seems I lost the direction completely.

I have JPEG versions of these pictures (4 or 5), so if anybody interested to
check then in their Photoshop or NikonScan I'll be glad to send them over.

Regards,
Alex Z

Are you sure altering color balance isn't "cheating"? ;-)

The film is probably recording a more accurate color temperature than
our eye does.  As you know, we color adjust chemically and reduce the
blue component we see in shadows.  If you were suddenly plunged into the
shadow after being in the bright yellow sunlight, you'd likely see the
shadows as very blue.
