Thanks Karl I'll have a play.
<BR>
WOuld anyone happen to have any references to the algorithms involved?

<P><EM>&gt; Take a look at vuescan. This application is used a lot among

<EM>&gt; serious &quot;film scanners&quot; (aka professional photographers).
</EM><BR>
<EM>&gt; IMHO the only thing missing in vuescan is the curve tool.
</EM><BR>
<EM>&gt;
</EM><BR>
<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>
<EM>&gt;
</EM><BR>
<EM>&gt; This is just one feature that makes or breaks a scanning application
</EM><BR>
<EM>&gt; for slides/negatives.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; You can download an evaluation version of vuescan from

<EM>&gt; There is a Windows, a Mac and a Linux version of the software.

<EM>&gt;&gt; negatives/slides? Any references on the web for what's required?

<EM>&gt;&gt;&gt;&gt; I don't think so. If proper strip film feeder functions (frame
</EM><BR>
<EM>&gt;&gt;&gt;&gt; selection) and decent dust removal are added to the backend, then SANE
</EM><BR>
<EM>&gt;&gt;&gt;&gt; will be just as good and useful as VueScan, as far as I can tell.
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt; VueScan does a whole pile of other things in the &quot;front&quot; end that make it
</EM><BR>
<EM>&gt;&gt;&gt; a far superior solution for scanning negatives. This is a bit hard to
</EM><BR>
<EM>&gt;&gt;&gt; separate as VueScan comes as a single program though. Things such as multiple
</EM><BR>
<EM>&gt;&gt;&gt; pass scans, auto croping, film loading, slide and negative gamma curves
</EM><BR>
<EM>&gt;&gt;&gt; and a whole pile more would be in a none existent Sane front end for
</EM><BR>
<EM>&gt;&gt;&gt; film scanners.
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt; Basically Sane needs a slide/negative front end, and I don't see one
</EM><BR>
<EM>&gt;&gt;&gt; in a usable state being available anytime soon. Lets face it there is
</EM><BR>
<EM>&gt;&gt;&gt; not even one in development. While XSane is great for a desktop scanner
</EM><BR>
<EM>&gt;&gt;&gt; for sheets of paper, photographs, you basic everyday reflective scanning,
</EM><BR>
<EM>&gt;&gt;&gt; it is entirely unsuitable for transmission scanning of negatives and slides.
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt; That is no reflection on XSane as the two are entirely different
</EM><BR>
<EM>&gt;&gt;&gt; propositions, and XSane is targeted at the more widely used reflective
</EM><BR>
<EM>&gt;&gt;&gt; scanning market. What is needed is a XFilmSane front end.
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt;&gt; In any case, there is no point giving up on the basis that there is a
</EM><BR>
<EM>&gt;&gt;&gt;&gt; better (commercial) alternative.
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt; You are of course quite right, but if it were me I would buy a copy of
</EM><BR>
<EM>&gt;&gt;&gt; VueScan while waiting/developing a negative/slide front end for Sane.
</EM><BR>
<EM>&gt;&gt;&gt;
</EM><BR>
<EM>&gt;&gt;&gt; At the moment if you are serious about scanning negatives and slides then
</EM><BR>
<EM>&gt;&gt;&gt; the only realistic option is VueScan.
