Well, I doubt that this is a backend problem, unless the Snapscan actually<br>
|
|
supports 12-bit or 16-bit per sample scans.<br>
|
|
<p>
|
|
Your JPEG images make the visual problem immediately apparent, but it is<br>
|
|
very hard to decide exactly what the cause of the problem is once JPEG<br>
|
|
has destroyed (yes -- really, destroyed) large parts of the image detail.<br>
|
|
Can you make lossless compressed TIFF files available somehow?<br>
|
|
<p>
|
|
I had some (limited, because of JPEG artifacts) success in enhancing the<br>
|
|
photos from your web page so that the SANE picture was closer to the one<br>
|
|
from Photolook. So at least some of the effect of Photolook is in the<br>
|
|
enhancement of the image after it has been transfered from the scanner.<br>
|
|
<p>
|
|
Probably more work is needed on Auto calibration (see XSane) or on the<br>
|
|
options and previews in the frontends. If the 310 has 12-bit or 16-bit<br>
|
|
modes, then the backend should support those eventually, but again there<br>
|
|
is no support in the graphical frontends (yet)<br>
