Infrared Dust & Scratch Removal for RAW Film Scans – Any Format, Any Scanner

Film scanning is more popular than ever — from personal archives to museum preservation. Many scanners (Nikon, Plustek, Epson, Pacific Image/Reflecta, etc.) can capture an infrared channel to detect dust and scratches. Software like SilverFast HDRi and VueScan RGBI can save RAW scan files (TIFF/DNG) with both the image data and the IR defect map.

Capture One currently cannot use this IR channel for cleaning. This forces users into a choice:

  • Use the IR cleaning in scanning software and lose RAW editing flexibility in Capture One, or

  • Keep RAW flexibility in Capture One but spend hours manually removing dust and scratches.

Adding infrared-based dust/scratch removal directly to Capture One’s RAW workflow would be a world-first in mainstream RAW editors, saving hours of work and making C1 the top choice for anyone digitizing film.

Current workaround

I currently run iSRD cleaning in SilverFast or IR Clean in VueScan, then export 48-bit TIFFs for Capture One. This preserves the cleaning but loses the white balance flexibility and tonal range of RAW files.

Alternatively, I skip IR cleaning and manually retouch dust in Capture One or Photoshop, which is extremely time-consuming for large archives.
