LaserSoft Imaging

I just install SilverFast to work with this scanner, but I can only see a working space of 6x4. I can't work with 6x7 or 6x9 negatives. How can I solve my problem?
Thanks

You are able to switch through the formats, but of course you need the specific multiformat adaptor to scan up to 6x9.

If you insert the multiformat adaptor you will see a button appearing with the format written on it. Click this button to switch to the desired format.
