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.
