LightZone Official Description
"LightZone is professional-level digital darkroom software for Windows, Mac OS X, and Linux. Rather than using layers as many other photo editors do, LightZone lets the user build up a stack of tools which can be rearranged, turned off and on, and removed from the stack. It's a 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 be copied to a batch of photos at one time. LightZone operates in a 16-bit linear color space with the wide gamut of ProPhoto RGB."
