FFF at a glance
FFF
Hasselblad's workflow tooling treated raw capture and high-end processing as parts of one integrated medium-format imaging environment, which is why formats like FFF survive in specialist archives.
J2K at a glance
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.
