What LightZone is
LightZone is a free digital darkroom and photo editor for Windows, macOS, and Linux. It processes RAW photographs and supports batch editing, but layer editing is not included. Its non-destructive tools can be rearranged, adjusted, switched off, removed, or revisited in a later session. LightZone works in a 16-bit linear color space with the ProPhoto RGB wide gamut, reads RAW files from various cameras, and displays metadata such as exposure, ISO, and flash. Listed tools include relighting, sharpening, blur, color and white balance, black and white, noise reduction, cloning, spot correction, and red-eye correction. Style filters include Alien Infrared, Skin Glow, and Polarizer. The project provides video training through YouTube and a GitHub discussion page. Its repository identifies a BSD-3-Clause license. Linux packages are provided for Ubuntu-latest and Fedora 43; packaging for every distribution, including AppImage and Flatpak, is outside scope. The LightZone plan costs nothing.
