PFM Raw in het kort
PFM Raw
PFM persists from the era when HDR imaging, rendering research, and tone-mapping workflows needed straightforward file carriers for floating-point image data long before mainstream consumer HDR delivery formats matured.
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.
