digiKam is a professional-quality photo management system. It supports a five-stage photographic workflow: import, organization, browsing, processing, and publishing. The import step is able to work with any digital camera supported by Gphoto2. This covers many hundreds of models, with a full list linked from the digiKam features page. The organize step allows users to group photos and videos into albums and sub-albums, each of which can carry comments and tags. The browsing mode supports lightbox-style side-by-side comparisons of pictures and offers a sidebar that displays comprehensive image metadata. Image processing support includes color correction and enhancement out of the box, with additional filters available as plugins. In the publication step, photos and albums can be exported to numerous services including Flickr, SmugMug, and Facebook. Additionally, albums can also be imported from Facebook and Shwup. digiKam executables are available for Windows, macOS, and Linux AppImage containers. Most Linux distributions also include a digiKam package. digiKam is free software, licensed under the GNU General Public License.
