UFRaw is a GUI for reading RAW files from digital cameras and compressing them to 8bit per channel low dynamic range images. UFRaw is based on the dcraw command-line tool and has the same capabilities.
There are two tools provided with UFRaw:
- A plugin for the gimp image editor allowing interactive opening of RAW files.
- A standalone GUI application, RAW files can be opened, levels adjusted and previewed before saving.
