I have been adapting Didiers Coolscan Backend for the LS-30/2000.<br>
|
|
It is still alpha, but the main functionality is there.<br>
|
|
<p>
|
|
On the hardware-side the dust-removal is implemented by a<br>
|
|
4th color channel (infrared) which only shows the dust.<br>
|
|
The software side is responsable for using that information<br>
|
|
to interpolate the occluded regions.<br>
|
|
<p>
|
|
The latest version of my backend together with a gimp-plugin<br>
|
|
that I wrote, includes a simple version of the dust-removal.<br>
|
|
It works, but it is not production code yet as there are some<br>
|
|
manual adjustments to do.<br>
|
|
<p>
|
|
You may have a look at my homepage for more details<br>

|
I am also working on getting 12 or 14 Bit images out of the LS-30<br>
|
|
(by multi exposure scanning) to further reduce noise in dark<br>
|
|
areas.<br>
|
|
To day the LS-30 is supported for 10 Bit scanning and the LS-2000<br>
|
|
for 12 Bit.<br>
|
|
Multiple scanning on the LS-2000 is not supported yet.<br>
|
|
<p>
|
|
If you consider buying a LS-30 or LS-2000, please ask Nikon about<br>
|
|
the scanners SCSI documentation BEFORE BUYING, saying<br>
|
|
it is very important to you to use it under Sane.<br>
|
|
All the work I have done on the Backends so far is<br>
|
|
without the docs!!!<br>
|
|
They have not replied so far to my request for documentation.<br>
