LightZone is image manipulation digital darkroom application which is available for cross-platform Linux, Windows and Mac, that includes RAW processing and editing. LightZone allows user to build up a stack of tools which can be rearranged, readjusted, turned off and on, and removed from the stack, it is different from other photography apps. It's a completely non-destructive editor, where any of the tools can be re-adjusted or modified later - even in a different editing session. A tool stack can even be copied to a batch of photos at one time. LightZone always operates in a 16-bit linear color space with the wide gamut of ProPhoto RGB.
