LightZone is a free image editing program, similar to DarkTable, and a good alternative for Adobe Lightroom, which is proprietary software. It has support for the most popular image formats, RAW included and may be a good choice.
The latest version available is LightZone 4.1.4, which brings changes.
- ToolStack dragging failure on Java8
- Null pointer exceptions when getting icc color profiles
- Strength of High Pass Filter tool was wrong when zoom scale was not 1:1
- ZoneFinder shows Zones at selected ZoneMapper now, without affected by subsequent tools

- Updated raw tone curve for Nikon D5300
