Hello Mailing-Listeners,<br>
<p>
I'm thinking to attached and enlarger to a scanner to project medium<br>
format negative on the scanner plate and scan them. This would increase<br>
the resolution and allow the scanning of whole medium format size<br>
negatives/slides whithout buying an more expensive, which could to do<br>
this directly.<br>
However, someone on rec.photo.equipment.medium-format (Johan Erasmus)<br>
tried this already and reported that the image, if visible at all, was<br>
very weak<br>
<p>
My questions:<br>
In what range can the scanner sensitivity by chosen by SANE? Arbritary<br>
or fixed exposure times?<br>
Which scanners support such manipulation of their sensitivity?<br>
<p>
Thanks a lot for your help.<br>
<p>
Regards,<br>
<p>
