History

SilverFast was introduced in 1995, it is still under development today. Some scanner manufacturers bundle their hardware with SilverFast software. Some of the features developed for SilverFast, especially in the area of

Products

SilverFast is offered individually adjusted to the respective scanner model. If several scanners are operated, it is therefore necessary to purchase a corresponding number of additional licenses. Upgrade rates are also offered when purchasing a new scanner. Overview of the available products: ¹⁾ including: Multi-Exposure ²⁾ optional: ICC Printer Calibration

Optional features

As marked in the table above, some products are available with additional features: Multi-Exposure – Multi-Exposure is an exposure blending technique for scanning transparent originals like slides, negatives, and film strips with increased

. This is accomplished by scanning the original multiple times with different exposure times, increasing the dynamic range and preserving detail in the light and shadow areas of the image. Multi-Exposure does not work with reflective originals and differs from "Multi-Sampling," which also scans multiple times but with unaltered exposure. ICC Printer Calibration – The SilverFast ICC Printer Calibration calibrates the printer using a previously calibrated flatbed scanner as the measuring device for profiling the printer.

HDRi (64Bit RAW data with infrared channel)

With version 6.6.1 any SilverFast HDR version supports the proprietary RAW data format HDRi. These 64-bit HDRi color files and 32-bit HDRi greyscale files contain additional 16-bit infrared RAW data besides the 48-bit color RAW data and 16-bit greyscale RAW data respectively. Therefore, a scanner with an infrared channel available to the software is necessary. This RAW format can keep any readable image information for later post-processing. The acronym "HDR" as used by SilverFast is not related to

SRDx Photoshop Plug-in

SRDx (Smart Removal of Defects) is a plug-in for Adobe Photoshop to remove defects like dust particles, specks, small scratches and finger prints from digital images. Most dust and scratch removal tools use blur effects which degrade overall image quality. SRDx works without any unsharping effects. SRDx uses an adjustable automatic detection of dust and scratches that can be fine-tuned manually using a defect marker and a rubber tool.

SilverFast DC

SilverFast DC has been discontinued. SilverFast DC was a stand-alone software for digital camera image processing. It contained features for reading the image data from the camera, for processing, optimizing, and archiving the images on the computer, as well as for printing the edited images.
