Olympus PEN-F RAW Files: Open, Cull & Edit .ORF Free

A retro-styled rangefinder body aimed at street photographers who valued its dedicated color and monochrome profile dial. That dial encourages a lot of in-camera style exploration on the same scene, which the RAW file discards in favor of neutral data. Reviewing those exploratory shots against the base RAW is the main editing task here.

Editing PEN-F files with imagic

imagic opens .ORF files from the Olympus PEN-F 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 18-22 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
