<p>Further to this, I get the same issue with digikam, which I
believe just uses the same sane/genesys backends as xsane?? </p>
<p>- so I _guess_ the issue with this Plustek (film/slide scanner)
may be there, rather than xsane per se.</p>
<p>In which case, is this forum the right place to ask for advice,
or is there somewhere more appropriate?<br>
</p>
<p>(I also guess that vuescan, which works ok, does not use sane
backends?)</p>
<p>Thanks again!<br>

Am attempting to use a Plustek 7200i scanner connected via USB
using xsane (0.999) frontend.

<p>xsane detects the Plustek scanner just fine, and completes
scans happily too. <br>
</p>
<p>However, with default / installation settings, the scanned
images appear to be clear in resolution but are <u>much</u>
too dark. </p>
<p>Playing with xsane settings (brightness / gamma etc)
mitigates this a little but not much. Behaviour is
consistent regardless of resolution of scan. <br>

<p>I'd be grateful for any suggestions. Could it be a
calibration issue??</p>
