SilverFast is the name of a family of software for image scanning and processing, including photos, documents and slides, developed by LaserSoft Imaging.

Contents

There are also other applications for image processing using digital cameras or printers and for 48-bit raw data image processing.

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 color management, error detection and automatic dust and scratch removal, have been patented. The European Digital Press Association named SilverFast the "Best colour management software of the year 2008" for improving the dynamic range of most scanners and for creating ICC profiles automatically. [2] In 2011 version 8 was introduced, and HDR imaging software followed in 2012. SilverFast 9 has been released in 2020.

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 dynamic range. [3] 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. [4] [5] 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.

SilverFast Scanner Software

It can be used as a stand-alone application, as a Photoshop plug-in, or as a universal TWAIN module. Versions include:

SilverFast HDR Software

SilverFast HDR is a computer program for processing 48-bit raw images. Many newer scanners are able to output the image directly with all existing data instead of breaking it down to 24-bit. This 48-bit raw image can be saved immediately and digital processing performed later.

SilverFast HDR contains the functionality of SilverFast Ai Studio for 48-bit raw data, such as defining output size and resolution, auto-adjusting of highlights and shadows, three-part histogram, gradation curves, selective color correction, unsharp masking, color cast removal slider, color separation, and CMYK-preview. SilverFast HDR can be used as a native plug-in for Adobe Photoshop, as a universal TWAIN module, or as a stand-alone application.

The HDR Studio has AACO (Auto-Adaptive Contrast Optimization), JPEG 2000, USMPlus (Unsharp Mask Plus), CloneTool and PrinTao.

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. [10] [11] 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 High-dynamic-range imaging, a widely used technique to increase the dynamic range of (digital) images.

The data format is:

SilverFast Archiving Software

The SilverFast Archive Suite includes SilverFast Ai Studio and SilverFast HDR Studio with an integrated color management system. This package is suitable for archiving slides, negatives, and photos, whereas the post processing can take place anytime after scanning. [12]

PrintTao 8

PrinTao 8 has been discontinued. PrintTao 8 was a software solution for Canon and Epson large format printers. It could be used as a stand-alone application or as a plug-in for Adobe Photoshop and Adobe Lightroom.

PrinTao 8 handled color management and all printer driver settings. It contained various printing templates like pack templates for portrait photographers or gallery wrap templates for printing on canvas.

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.

IT8 calibration & color management

Scanner calibration: SilverFast is equipped with a color management system that enables largely automated IT8 color calibration of the scanner using IT8 targets supplied by the manufacturer LaserSoft Imaging.

Printer calibration: SilverFast also enables printer calibration by printing a color table and then scanning it using an already calibrated scanner to create an ICC profile.

Supported devices

SilverFast supports 325 scanners. [15] Most Microsoft Windows-only 35mm USB scanners sold under various names are not supported[ citation needed ]. Each scanner model requires a separate license.

Heidelberg drum scanner

SilverFast Ai Studio supports prepress drum scanners made by Heidelberger Druckmaschinen AG (Linotype - Hell) on Microsoft Windows 2000, XP, Vista and 7, as well as Mac OS X 10.3-10.5 operating systems. Supported models include the Chromagraph 3300/3400, Tango/XL, Topaz, Nexscan, and Primescan.

In computer graphics and digital photography, a raster graphic represents a two-dimensional picture as a rectangular matrix or grid of pixels, viewable via a computer display, paper, or other display medium. A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats.

<span class="mw-page-title-main">Multi-exposure HDR capture</span> Technique to capture HDR images and videos

In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images by taking and combining multiple exposures of the same subject matter at different exposures. Combining multiple images in this way results in an image with a greater dynamic range than what would be possible by taking one single image. The technique can also be used to capture video by taking and combining multiple exposures for each frame of the video. The term "HDR" is used frequently to refer to the process of creating HDR images from multiple exposures. Many smartphones have an automated HDR feature that relies on computational imaging techniques to capture and combine multiple exposures.

<span class="mw-page-title-main">Image scanner</span> Device that optically scans images, printed text

An image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.

Preview is the built-in image viewer and PDF viewer of the macOS operating system. In addition to viewing and printing digital images and Portable Document Format (PDF) files, it can also edit these media types. It employs the Aqua graphical user interface, the Quartz graphics layer, and the ImageIO and Core Image frameworks.

<span class="mw-page-title-main">Multiple exposure</span> Superimposition of two or more exposures to create a single image

In photography and cinematography, a multiple exposure is the superimposition of two or more exposures to create a single image, and double exposure has a corresponding meaning in respect of two images. The exposure values may or may not be identical to each other.

<span class="mw-page-title-main">High-dynamic-range rendering</span> Rendering of computer graphics scenes by using lighting calculations done in high-dynamic-range

High-dynamic-range rendering, also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with more simplistic lighting models.

Digital "darkroom" is the hardware, software and techniques used in digital photography that replace the darkroom equivalents, such as enlarging, cropping, dodging and burning, as well as processes that do not have a film equivalent.

An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or lossless compression. For graphic design applications, vector formats are often used. Some image file formats support transparency.

A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are so named because they are not yet processed, and contain large amounts of potentially redundant data. Normally, the image is processed by a raw converter, in a wide-gamut internal color space where precise adjustments can be made before conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment.

A motion picture film scanner is a device used in digital filmmaking to scan original film for storage as high-resolution digital intermediate files.

The aim of color calibration is to measure and/or adjust the color response of a device to a known state. In International Color Consortium (ICC) terms, this is the basis for an additional color characterization of the device and later profiling. In non-ICC workflows, calibration sometimes refers to establishing a known relationship to a standard color space in one go. The device that is to be calibrated is sometimes known as a calibration source; the color space that serves as a standard is sometimes known as a calibration target. Color calibration is a requirement for all devices taking an active part in a color-managed workflow and is used by many industries, such as television production, gaming, photography, engineering, chemistry, medicine, and more.

High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual.

Linux color management has the same goal as the color management systems (CMS) for other operating systems, which is to achieve the best possible color reproduction throughout an imaging workflow from its source, through imaging software, and finally onto an output medium. In particular, color management attempts to enable color consistency across media and throughout a color-managed workflow.

<span class="mw-page-title-main">HDR PhotoStudio</span> Discontinued graphics application

HDR PhotoStudio is a discontinued high dynamic range (HDR) graphics application developed by Unified Color for the Windows and macOS operating systems. In addition to being a HDR-merge application, HDR PhotoStudio offered a set of image editing operations that worked in its dynamic range, human color range (gamut), and in high precision. It also had a Color Integrity feature that enabled preserving an image's color tone during image editing operations — for example changing an image's contrast would not change its chromatic data. This problem is usually referred to as "color shift".

<span class="mw-page-title-main">Spirit DataCine</span> Motion picture film scanner

Spirit DataCine is a telecine and a motion picture film scanner. This device is able to transfer 16mm and 35mm motion picture film to NTSC or PAL television standards or one of many High-definition television standards. With the data transfer option a Spirit DataCine can output DPX data files. The image pick up device is a solid state charge-coupled device. This eliminated the need for glass vacuum tube CRTs used on older telecines. The units can transfer negative film, primetime, intermediate film and print film, stock. One option is a Super 8 gate for the transfer of Super 8 mm film. With a sound pick up option, optical 16mm and 35mm sound can be reproduced, also 16mm magnetic strip sound. The unit can operate stand alone or be controlled by a scene by scene color corrector. Ken Burns created The Civil War, a short documentary film included in the DVD release, on how he used the Spirit DataCine to transfer and remaster this film. The operator of the unit is called a Colorist or Colorist Assistant. The Spirit DataCine has become the standard for high-end real-time film transfer and scanning. Over 370 units are used in post-production facilities around the world. Most current film productions are transferred on Spirit DataCines for Television, Digital television, Cable television, Satellite television, Direct-to-video, DVD, Blu-ray Disc, pay-per-view, In-flight entertainment, Stock footage, Dailies, Film preservation, digital intermediate and digital cinema. The Spirit DataCine is made by DFT Digital Film Technology GmbH in Darmstadt, Germany.

<span class="mw-page-title-main">Image color transfer</span> Function that maps the colors of one image to the colors of another image

Image color transfer is a function that maps (transforms) the colors of one (source) image to the colors of another (target) image. A color mapping may be referred to as the algorithm that results in the mapping function or the algorithm that transforms the image colors. The image modification process is sometimes called color transfer or, when grayscale images are involved, brightness transfer function (BTF); it may also be called photometric camera calibration or radiometric camera calibration.

<span class="mw-page-title-main">Exposure fusion</span>

In image processing, computer graphics, and photography, exposure fusion is a technique for blending multiple exposures of the same scene (bracketing) into a single image. As in high dynamic range imaging, the goal is to capture a scene with a higher dynamic range than the camera is capable of capturing with a single exposure.
