it should be possible to make a 48BIT HDR Scan save it as tiff file and than import it into Lightroom.
Please note that Negative film scanned in that way will not be converted to positive.
You also got the option to use SilverFast HDR to apply changes to your RAW scans and have the abillity
to use all the original SilverFast tools after the Scan with SilverFast HDR.
