LightZone is professional-level digital darkroom software , a non-destructive editor, where any of the tools can be re-adjusted or modified later - even in a different editing session. LightZone was created by Light Crafts, Inc., as proprietary software, and was sold starting in 2005. It released LightZone to open source in December 2012.
