PEF in het kort
PEF
Pentax raw workflows never dominated the mass market, but their persistence in enthusiast and specialist photo libraries gives PEF ongoing practical relevance.
DDS in het kort
DDS
DDS grew out of Microsoft's graphics API and game-development ecosystem, which is why it feels more like an engine or texture-delivery format than a conventional consumer image file.
