Karl Heinz,
<BR>
<P><EM>&gt; If you want to scan negatives, you need a library of rules to remove
</EM><BR>
<EM>&gt; the orange mask for all sorts of films. In vuescan you select the
</EM><BR>
<EM>&gt; brand (e.g. Kodak) and then the type of film (e.g. Gold) and then
</EM><BR>
<EM>&gt; the emulsion revision (e.g. 6), so it's a rather sophisticated
</EM><BR>
<EM>&gt; algorithm to remove the mask.
</EM><BR>
<P>If it's only the mask, I think it should be rather easy to take into
<BR>
account: scan an unexposed part of the film, this gives you the mask
<BR>
only, then you know what you have to correct the other parts of the
<BR>
image with in order to get rid of the mask.
<BR>
<P>Do you know where the mask physically comes from?
<BR>
<P><EM>&gt; This is just one feature that makes or breaks a scanning application
</EM><BR>
<EM>&gt; for slides/negatives.
</EM><BR>
<P>Are there any others?
<BR>
