LightZone unveiled
at DEMOfall 2005 unveiled LightZone for Mac OS X, its photo editing software designed to process images in terms of light and objects instead of pixels. LightZone offers the "StudioFinder" image viewer and file browser that organizes, prints, and publishes photographs using a "true digital negative format." The software also incorporates "ZoneFinder" image analysis, "ZoneMapper" for light/tonal adjustment, "RegionMapper" for area/shape selection, non-destructive editing that treats the original image as a digital negative, and linear color space instead of a gamma-corrected color space for consistent color and predictable results on a display or on paper (LightZone system requirements, pricing, and availability were not available).
