 You are right. I wrote a custom driver which does IR (well, kind of;
 that is my problem) and at the same time talking with Gernot about the
 SANE 8800F driver. As often suggested a custom driver is easier when
 exploring a unknown scanner but the solution may later be transportable
 into SANE. Need that solution first.

Hello Enno,
  Can you tell me if the Windows driver has this capability at all? I
tried with positives and negatives, but only found options for color
and greyscale, not other scan modes.

Regards,
Gernot

The options I can see in color negative scan mode are (translated as
best I can):

1) auto color adjust
2) contour/silhouette/edge enhancement
3) dirt removal (using FARE)
4) discolouration correction
5) graininess reduction
6) glare correction

I haven't checked all/any of these except to note that auto color
adjust appears not to be hardware, there is no difference in the
command block to the scanner.

Regards,
Gernot

FARE is the Canon word for the Infrared scanning, Dirt removal should do
a scan with D8 20 data[0] = 03 ie. infrared. (01 flatbed, 04 film rgb)

2010-03-27 Thread Enno Fennema
I am scanning negatives on a Canon scanner, both normal RGB and then
infrared. The alignment of visible dark (light after inversion) patches
in rgb and the IR patches is poor and varies in a for me unpredictable
way from patch to patch.

Would like to get in touch with anyone having similar results or
suggestions or even solutions.

Regards,
Enno

Uhm- how are you scanning IR in sane with an unsupported scanner?

well, then I would start with windows snoops of the IR in action, and
make sure you are sending the same commands.
