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.
DNG at a glance
DNG
DNG emerged when professional photo workflows were already fragmented across many undocumented vendor raw formats. Adobe positioned it as a common archival and interchange option rather than just another camera-native format.
