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.
PGX at a glance
PGX
These formats persist in engineering, compression research, and conversion-tool contexts where simple sample storage or adjunct technical representation is useful.
