Editing D750 files with imagic
imagic opens .NEF files from the Nikon D750 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 22-28 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
