J2K in het kort
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
NEF in het kort
NEF
NEF spans the long Nikon digital-camera era, from early DSLRs through modern mirrorless bodies, which is why its compatibility history matters so much in archive and editing workflows.
