SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video and still cameras, framegrabbers, etc.). The SANE standard is public domain and its discussion and development are open to everybody. The source code is written for UNIX (including Linux) and is available under the GPL, but commercial applications and backends are welcome. The package contains the libraries, net support, and scanimage. The X frontends xscanimage and xcam can be found in sane-frontends.
digiKam is an advanced digital photo management application that makes importing and organizing digital photos a trivial task. Photos can be organized in albums, which can be sorted chronologically, by directory layout, or by custom collections, and they can be tagged, commented, and rated. digiKam makes use of a fast and robust database to store meta-information, which makes adding and editing comments and tags very reliable. Metadata can also be stored inside pictures using Exif and IPTC. An embedded image editor and a standalone application named showfoto have simple but powerful features for editing your pictures with filters and correction tools.
My Photo Gallery is a Web-based photo gallery that also supports non-image filetypes. It is easy to setup and even easier to maintain. Slick-looking image galleries and thumbnails are generated on the fly from any root directory that you specify. Albums can be created using the included Web-based adiminstration tool or by creating a directory and copying your pictures and files to that directory. A Web administration interface is available to help add descriptions, rename images, rotate images (losslessly), and more. It includes advanced features such as image logging, renaming, resizing, image rotation, smilies, and visitor comments. Unlimited filetypes may be recognized, and custom images for them can be displayed in your galleries, allowing you to archive MP3s, MPEGs, AVIs, etc.
LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). LibRaw is based on the source codes of the dcraw utility, though some of the drawbacks of dcraw have been eliminated. The users of the library are provided with an API to be used when writing their software programs.
This package contains frontends to SANE ("Scanner Access Now Easy"), including xscanimage, xcam, and scanadf. Xscanimage is a GTK-based application for scanning images that can also be used as a GIMP-plugin. Xcam is used to get images from cameras supported by SANE. Scanadf is a command line frontend especially suited for scanners equipped with automatic document feeders (ADF).
Exiv2 is a C++ library and a command line utility for managing image metadata. It provides fast and easy read and write access to the Exif, IPTC, and XMP metadata of images in many formats. The Exiv2 command line utility prints Exif, IPTC, and XMP metadata including Makernote tags in various formats, adjusts Exif timestamps, renames images according to the Exif timestamp, extracts and inserts Exif, IPTC, and XMP metadata and JPEG comments, or deletes the thumbnail or a specific type of metadata from an image.
Remote Capture for Canon PowerShot cameras is a tool for controlling Canon PowerShot cameras. It has been tested with the following Canon PowerShot cameras: S50, A60, A70, A75, A80, A85, A95, A510, A520, G6, S400, S410, and S500. The main advantage of Capture compared to gPhoto is that the consecutive shots are taken without the camera lenses being closed and opened again. When taking several thousand shots in a row, this indeed lets the camera live longer. If you do not need this feature, gPhoto is sufficient.
