As an immediate but less ideal solution you could use xsane (see<br>
|
||
<a href="http://www.wolfsburg.de/~rauch/">http://www.wolfsburg.de/~rauch/</a><br>
|
||
) which has separate R, G and B gamma's. But if you need a large<br>
|
||
gamma then you will amplify the scanner noise an awfull lot.<br>
|
||
<p>
|
||
I'm curious about the slides, are they underexposed, and do they look<br>
|
||
purple when holding them to the light? If you could send me a raw scan<br>
|
||
(say at 300 dpi) I would appriciate it. I'm writing a new frontend<br>
|
||
that is especially tailored towards filmscanners.<br>

The garbage at the bottom is a known problem with the photosmart.<br>
