LightZone is a free, open source digital photo editor software application. It was originally developed as commercial software by the now-defunct Light Crafts. Its main purpose is to handle the workflow when handling images in various RAW formats. It is comparable to Adobe Systems's Photoshop Lightroom.
Versions for Windows, Mac OS X and Linux were available commercially. Although the Linux version was free of charge in earlier versions, its price was adapted with the 3.5 release.
In mid-September, 2011, the Light Crafts website went offline without notice. It is reported that Fabio Riccardi, founder of Light Crafts and the primary developer of LightZone, is now working as an Apple employee, as evidenced by his LinkedIn profile. The final version from Light Crafts was version 3.9, except for Mac OS X which had a bug-fix version 3.9.2. On-going LightZone support, including updates to let LightZone process Raw files from new camera models, is being provided by the volunteer LightZombie Project.
