We do a lot of high quality, high resolution scans on our Hasselblad X1 high end scanner. It undoubtably brings the best out of negatives (and postives), but the downsize is that all microscopic dust particles, scratches etc. also appear very sharp when you zoom in to 100%. Therefore Mikkel just did a small video to show how he does dust removal in Photoshop.
Dust on the brain -- dust removal on high resolution scans from bjarke ahlstrand on Vimeo.
The negative was shot on a Hasselblad Xpan with 45mm f4 on expired (1994!) Kodak Technical Pan film, rated at ISO12 and developed at OOMC, and then scanned on our Hasselblad X1 scanner. Mikkel removed dust in Adobe CC.
