Canon EOS R6 RAW Files: Open, Cull & Edit .CR3 Free

A low-light and event-focused body with dual SD slots and fast burst rates, popular with wedding and reportage photographers. Lower resolution than the R5 keeps files smaller even at high frame rates, but event days still produce large take volumes across ceremony, speeches, and reception coverage. Automated scoring across that volume is what keeps next-day delivery realistic.

Editing EOS R6 files with imagic

imagic opens .CR3 files from the Canon EOS R6 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 20-27 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
