If you're in search of an open source photo organizer for the GNOME desktop environment, Shotwell is worth a look. It imports pictures from your digital camera for easy organization and editing.
Although the Shotwell project is quite new, the app sports several important functions you'd expect to find in tools of this kind. Users can reduce red-eye and adjust an image's exposure or saturation, or simply auto-enhance it in a single click. Shotwell also rotates, mirrors, and crops photos, and exports files as they are or according to user presets to reduce their size.
Currently, Shotwell 0.3.0 works only on Linux, but an upcoming release will include a Windows installer, along with a number of interesting new features. "In 0.4 you'll be able to upload photos to Flickr and Facebook, to move photos between events, to display extended information about photos, and much more," writes Shotwell developer Adam Dingle.
Created by San Francisco-based software company Yorba, this isn't the team's first foray into multimedia application development. They've also designed a video editor and multitrack recorder GNOME in keeping with the goal of making it "as easy to work with media using Linux as on a Mac or Windows computer."
