I recently reported on the Plustek 120 scanner for scanning B&W film.
After reading about my positive experience with the Plustek 120, my friend Mark purchased one. Mark, being a Master in film processing, develops both B&W and colour film. While using the colour film dust removal feature of the Silverfast sofware, he initially found things weren’t working. However, a few quick changes in Silverfast solved the problem.
“I appear to have a fix for the problem… It seems that there is a setting under [Silverfast’s] “Preferences > Special > Maximum Offset for iSRD alignment” that is “Maxed Out” by default. I have decreased my value to 50 (from a default of 70) and decreased the detection threshold to 2 (in the iSRD Dialogue) and the resulting correction is PERFECT, with no alterations in the underlying grain structure of the resulting scan…I hereby declare this to be a FINE scanner…“
Thank you for this information Mark.
