	SilverFast – SRDx Dust and Scratch Removal of a new Generation
SRDx - Presentation SRDx - Tutorial SRDx Manual Now available as Photoshop Plug-in	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. Greater 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. 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. 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 Mask Tool for limiting correction effects to certain image areas (Click to enlarge) Special Tools in Expert Mode The expert mode (only in Ai Studio, HDR Studio and the Archive Suite) offers additional functionality, which helps to mark the defects to be corrected. With the Marker Tool, the correction intensity of individual image details can be selectively decreased or increased. The Eraser Tool is used to specify image areas, where no correction should be applied at all. Marker Tool decreasing and increasing intensity Eraser Tool for protecting important image areas Requirements for using SilverFast SRDx Included with every SilverFast Scanner and HDR Software Special Tools only in SilverFast Ai Studio and HDR Studio 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, ICE¹, FARE¹ or MagicTouch¹ can not be used here. SRDx has been developed especially for these cases. SRDx ensures an effective removal of dust and scratches even for B/W film and Kodachromes. Movies: Upgrade to Ai Studio or HDR Studio Experience with our movies, why the upgrade to Ai Studio or HDR Studio is worth it and how easy it is to use the SRDx special tools! Infrared-based dust and scratch removal iSRD Do you have analog images to scan and our 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.

« What makes the new SRDx tool so attractive is that it brings a very effective method of cleanup to those who do not have scanners with Digital Ice or its equivalent (many of which require a hardware/software combination) and especially for black-and-whites and Kodachromes, which Digital Ice cannot handle. In using the software, I found the fine tuning impressive. It eliminates the flaws that auto-correct (thus overdone) cleanup protocols often render. Another bonus is that the tool also works with print scans, which I believe will be a boon for retouchers as well as those who want to delve into the family archives. » George Schaub, Shutterbug Read the full article on www.shutterbug.com.
