Free, open source RAW image processor with fine-grained controls
RawTherapee is a free, open source program for developing RAW photos on Windows, macOS and Linux. It focuses on image quality, with several demosaicing algorithms, advanced noise reduction, color management and detailed tone and color tools, all applied non-destructively through processing profiles. It includes a file browser and batch queue but no catalog, so it suits photographers who organize files themselves.
