Hi,
I have a brand new[*] Nikon CoolScan III (aka LS 30)
I re-built and installed sane from the source, using
sane-backends-1.0.7-cvs-2002-05-02 and
sane-frontends-1.0.7-cvs-2002-05-02 on my Linux PPC system.
I started xsane 0.84. The scanner gets recognized by both coolscan and
coolscan2. Scanning do work flawessly, but I get really disappointing
scans:
-from negative film, color is really weird. This is the positive
image, but they really don't match. I selected "Kodak negative" as
media type.
-from black and white negative, picture is really dark, and really
grainy, and no that is not the film grain. I selected "Slide" and told
to invert after scanning, because I don't have B&W negative type.
-from slide film, I still get grainy pictures (even though I'm
scanning Provia or Velvia slide, both really common and one of the
most fine grained films). I selected "Slide" as media type.
In the three cases, the contrast is excessive. This is even more
visible on slides taken by real sunny day.
So my question is:
Is it a known issue ? If yes, what can I do to help resolve the
problems ? I can do whatever you want including debugging, coding and
taking pictures :-))
I'd really like to use my coolscan with SANE.

[*] I now this is the old model. That was a real bargain :-) given its
quality.
