iSRD on Plustek 8200i and Silverfast
I've been playing with my new Plustek 8200i and Silverfast. I've been able to get some pretty nice scan of my negatives, but the iSRD functionality of Silverfast really has me flummoxed (which is irritating as I spent extra money to get this functionality as I thought it would be useful).
Basically running an iSRD scan works as it should. However, most of the time the iSRD completely corrupts the final image, producing something akin to a stained-glass window. Looking at Silverfast's interpretation of the IR-scan, it appears to mark defects across the whole of the image - so the corruption isn't surprising. On a very (very) few occassions I've been able to get the iSRD function to do something vaguely sensible and mark a few of the defects, although its automatic correction leaves a lot to be desired and the actual detection doesn't appear to be significantly affected by any of the controls on the iSRD panel.
I've tried a fair few negatives now - all of them C41-process so I'm fairly certain there's nothing unusual about them.
I've also tried the trial version of VueScan - that doesn't seem to suffer the same issues as Silverfast with it's IR scans, but I'd really prefer not to have to pay for a new bit of software when the bundled one is meant to work.
Does anyone else have success with iSRD on a Plustek scanner? If so, are there any tricks or tweaks?
Thanks for any help that can be offered.
