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.
X3F in het kort
X3F
Sigma raw support is closely tied to the company's Foveon sensor story, giving X3F a reputation and workflow profile that differ from more mainstream Bayer-centric raw ecosystems.
