Dust and Scratch Removal of a new Generation

Photos, slides and negatives are naturally afflicted with image defects. Even if photos and slides are handled very carefully, it's virtually impossible to avoid contact with dust particles; small scratches are also not uncommon.

All dust particles have been removed with SRDx

Defects on treasured images can be especially annoying, because they often hide important details or even destroy the overall image. These flaws do not often get recognized until scanning, because scanning means also increasing image size in most cases. SRDx is the most efficient solution for the elimination of all these flaws and can also very efficiently eliminate unwanted image disturbances where infrared-based solutions cannot help.

SRDx is ideal for the following image originals

  • Black-and-white Film

  • Kodachrome Film

  • Photo prints

  • Digital camera images

How is SilverFast SRDx working?

The algorithms used in SRDx for defect detection can recognize dust and scratches because their image information differs greatly from the surrounding area.

Furthermore, the algorithm has been programmed to recognize typical scratch marks (elongate and narrow). Detected flaws can be removed by taking the surrounding image information into account. Other software solutions for removing dust and scratches usually use a focus blur, which deteriorates general image quality.

Using the image processing software SilverFast HDR and HDR Studio and SRDx you can eliminate defects from previously scanned images (also RAW data). You can also load and optimize digital images, for example from a digital camera. Many options to adjust the SRDx tool with simultaneous visual checking offer a reliable technique for removing any defects without destroying image details.

Further features of SRDx are:

  • Slider control for intensity of detection and correction

  • The preview window shows identified defects marked in red

  • 1:1 and HQ preview for exact evaluation

B/W Film & Kodachrome

Special Case: Black-and-White and Kodachrome film with infrared-based defect removal iSRD

A special case regarding dust and scratch removal are black and white film and Kodachrome film. Unlike color slides or color negatives, the scanner’s infrared rays can not permeate through the film emulsion, due to the silver halide layer contained in the film. This means that infrared based tools like iSRD, ICE, FARE or MagicTouch can not be used here.

SRDx, our software-based dust and scratch removal, has been developed especially for these cases. SRDx ensures an effective removal of dust and scratches even for B/W film and Kodachromes.

Additional Feature: iSRD

iSRD – our infrared-based Dust and Scratch Removal: Would you like to scan color film or color negatives and your scanner features an infrared channel? In this case we recommend to take advantage of the outstanding capabilities of our infrared-based dust and scratch removal iSRD.
