Hi all,
after some research I can see that this can be similar problem to this
one reported long time ago :

Does anybody have idea how this can be resolved ?
How autoexposure/enhancement can be set-up to be correct and resemble
to what iscan is doing ?

Can this be used :
http://www.xsane.org/doc/sane-xsane-setup-enhancement-doc.html
or these setting should be used only for lineart (i.e. commic scans)
and not for film negative scans ?

Thanks for any hints !

Best regards,
Drasko
