Sony ARW: The RAW Format for Alpha Shooters
Sony's RAW format is ARW (Alpha Raw), used across the full Sony Alpha range from the A7 series full-frame cameras to the APS-C A6000 series and professional A9 sports cameras. ARW files store complete sensor data and come in compressed and uncompressed variants, supported by all major free editing tools.
The Free Adobe Alternative Stack for Sony
Many Sony photographers default to Lightroom because Sony's own Imaging Edge software is limited. A completely free stack handles ARW files just as well.
imagic for Sony ARW Culling
imagic supports ARW files from all Sony Alpha cameras. Install with pip install imagic. The AI Analyse step processes your ARW files and scores every image for sharpness, exposure, noise, composition, and detail. Burst sequences are grouped and pre-sorted automatically.
imagic works on Windows, macOS, and Linux. The desktop version is a one-time $10 payment with no ongoing subscription.
darktable for ARW Editing
darktable handles Sony ARW files well. Its colour calibration module includes profiles for Sony cameras, and the editing pipeline manages Sony's characteristically wide dynamic range effectively.
RawTherapee for ARW
RawTherapee provides excellent ARW support including Sony's compressed RAW variants. imagic integrates with RawTherapee, so culled ARW selects can be sent directly for final processing.
Sony Imaging Edge
Sony's own Imaging Edge software is free and provides accurate Sony colour rendering. Pair it with imagic for culling to get AI-powered selection speed combined with Sony's precise in-camera colour science.
Sony-Specific Workflow Notes
- Keep your darktable or RawTherapee version up to date for compressed ARW support from newer cameras
- Sony's real-time tracking autofocus produces consistently sharp burst sequences; imagic's sharpness scoring reflects this with high scores across burst groups
- ARW files captured at high ISO benefit significantly from AI noise reduction after culling
