Fujifilm GFX 50S II RAW Files: Open, Cull & Edit .RAF Free

An affordable entry point into Fujifilm's medium-format system, aimed at studio and landscape photographers upgrading from full-frame. Shoots stay deliberate given the format, but bracketed and tethered product sequences are common. Sorting those sequences before processing avoids wasted time on very large files that will not make the final edit.

Editing GFX 50S II files with imagic

imagic opens .RAF files from the Fujifilm GFX 50S II 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 60-75 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
