WebbThis means a removal of dust and scratches with hardware support similar to iSRD is technically not possible. A good way to remove defects in a scanning workflow using a Flextight scanner such as the X1, the X5 or even the older Precision models offers SRDx as a plug-in for Photoshop. WebbFor positive and colour negatives I find that the scanner's infrared dust removal does such a good job that my need for manual dust-spotting in post is very limited indeed. In fact, if there is so much gunk on the (non-B&W) negative that Lightroom can't deal with it after this one really should physically clean the film and re-scan. –
