IIQ at a glance
IIQ
Phase One positioned IIQ around its medium-format and digital-back workflows, which is why IIQ appears in a very different professional context from ordinary consumer camera raws.
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.
