Hello Mailing-Listeners,

I'm thinking to attached and enlarger to a scanner to project medium
format negative on the scanner plate and scan them. This would increase
the resolution and allow the scanning of whole medium format size
negatives/slides whithout buying an more expensive, which could to do
this directly.
However, someone on rec.photo.equipment.medium-format (Johan Erasmus)
tried this already and reported that the image, if visible at all, was
very weak

My questions:
In what range can the scanner sensitivity by chosen by SANE? Arbritary
or fixed exposure times?
Which scanners support such manipulation of their sensitivity?

Thanks a lot for your help.

Regards,

Markus
