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.

does it have a noise removal option? allan On Sun, Mar 28, 2010 at 7:42 AM, Gernot Hassenpflug aikishugyo at gmail.com wrote: On Sun, Mar 28, 2010 at 2:29 AM, m. allan noah kitno455 at gmail.com wrote: well, then I would start with windows snoops of the IR in action, and make sure you are sending the same commands. allan On Sat, Mar 27, 2010 at 1:18 PM, Enno Fennema e.fennema at tiscali.nl wrote: m. allan noah wrote: Uhm- how are you scanning IR in sane with an unsupported scanner?

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.

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
