Sony A7R IV RAW Files: Open, Cull & Edit .ARW Free

The first full-frame mirrorless body to break 60 megapixels, used heavily in commercial, product, and landscape photography where cropping room matters. Files this large make storage and processing time real considerations even on modest-sized shoots. Culling before opening any files is less a convenience than a practical necessity at this resolution.

Editing A7R IV files with imagic

imagic opens .ARW files from the Sony A7R IV natively on Windows and macOS. Point it at a card or shoot folder and it builds previews, scores every frame for sharpness, closed eyes, and composition, and groups near-duplicate bursts — so a full shoot collapses to its keepers before you edit anything.

Processing runs through the bundled RawTherapee engine, entirely on your machine: batch-apply one look across the keepers and export JPEGs in a single pass. Nothing uploads, which matters at about 50-62 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
